Ok, I thought it was the multi switch in the steering column, replaced that and I still have an issue, Here is the problem.

There are some aftermarket fog lamps wired into the factory fog lamps and they work when you pull the run light switch ( on the dash ) on at the first position, Then the second position turns on the headlights.

Now when you pull back on the directional lever to turn on the high beams, the switch clicks but as you release it the high beams dont stay on? I dont understand why but the passenger high does not work at that time?

When the fog lamps ( running lights ) are on both the high beams will flash with the lever, and when no lights are on both high beams will flash. But when the headlights are on, only the drivers side high beam will flash?

I am baffled with this, and I need to get the truck inspected soon so I can street it,,,, What do I do? :doh:
Thanks In Advance for any help.

Sorry to hear the multifunction switch didn't take care of the problem. I had an intermittent issue with my headlamp switch that would have the fogs turning off if I hit a bump on my 2006 RAM. Had the dash switch replaced and that fixed my problem.

Check the ground wire on the passenger side headlight.

Ground is good as the light works any other time...is there some sort of relay under the hood for the high beams? Everything in the fuse panel is good.

I do not have experience or wiring information on your model year, so am only applying general wiring experience. I recently had a similar issue with a 2006 Chevy van, and the culprit turned out to be a faulty ground wire connection right at the headlight bulb. In this case, the light on the affect side was 'slightly' dimmer than the properly working counterpart. Are your lights of equal brightness on each side when working?

Yes, equal brightness, just the highs flash when you pull the lever in all positions with the fogs on, with headlights on the passenger doesnt work and the highs wont stay on? I am dreading taking it in for repairs as money is really tight...

Ok, I took a little video of what it does, as you can see the fog and aux. lamps run together ( wire tapped ) and they go off with the headlights on or flashing the high beams ( see both lights work at this time )
Then while headlights are on and you flash the high beams only the drivers work and the high beams will not stay on no matter what.... I looked, wiggled all the wiring with no luck of any shorts or anything, could it be the dash light switch? I heard on the 97 there were no headlight relays and everything ran from the headlight switch?? Thanks for any help and responses on this issue in advance. Great bunch here and a great atmosphere on the site !!!!

Where's the video? :4-dontknow: The dash switch feeds power to low and high beam circuits from the same source, so I doubt that's it.

I agree with RamTech that it is not the light switch itself. As he indicated, it is a global connection, so failure there would affect all the lights.

Based on the symptoms you described and watching the video many times, I noticed the right side never changes beams at all. So at this stage, I can't tell for sure if it's the low beam that's working, or the high beam. It may be adjusted to lower the high beam if that is the working beam, but for speculation sake, lets assume it's the low beam that is working.

I don't have the wiring diagram for 1997, but have one for 2001, and it may be very similar if not exactly the same. Hopefully RamTech can confirm whether or not I can use this diagram for a '97 Ram. so everything I am referring to is based on this 2001 diagram.

I believe you are dealing with 2 distinct problems. One is the non-functioning beam, and the other is the 'not staying on high beam'. The latter I would have suggested the multi-function switch, but you indicated that you have already replaced it, so just throwing it out there.....is there any chance that the multifunction lever is the type that you pull for 'flash to pass' and push to lock in the high beams?

Now for the missing beam. Check the orange wire with the Red stripe from the back of the right headlight to it's splice location under the PDC (Power Distribution Center...AKA Fuse Box). This wire should have 0v (ground) when the high beams are selected. Since this slice point connects to both high beams, I figure the wire from it to the right headlight has been compromised....or the actual connector on the back of the headlight. :4-dontknow:

Ok, 11pm and Im still thumped.... got it to work half azz'd...
I bought a new dash switch but that wasnt the issue, the wires were all cut and nutted so I soldered them and heat shrunk them, but there was a green wire cut and a wire ran to a purple with white stripe under the battery? when I took the red wire off, nothing worked?? but when I put the green wire back together the high beams come on and stay on with the lever and operate corectly but nothing else works???? So if I took that wire hooked to the purple with wite and hooked it to the fog lamps hot side I get headlights with the dash switch but when I hit the high beams the headlamps as well as the fogs go off? Man o man I was getting turbed tonight with this crap. I tried everything to no advail. I have to keep the fog lamp button on to have the headlamps and highs to work properly but the head/fogs are tied together and kinda screwy but it will pass inspection as far as I can see....so I will mess with it some more later down the road....But please still give your thoughts.inputs and info on it as it is not 100% correct yet. Here are some pics...

First off - The information I am providing here is based on the wiring manual for a different year, so there may be discrepancies. Use this information 'At Your Own Risk'.

It appears that someone has done some 'creative' wiring in a past life of this truck. That increases the challenge. Wish I could be 'hands on', I like challenges like this.

The 2001 wiring manual shows the following wire colors and what they connect to. Not sure if this helps, but if you can trace some of them and verify the accuracy, it may help sort the mess a bit.

Black / Orange (18ga) - Ground
Light Green (18ga) - Switches ground to multi switch to turn on headlights.
Pink / Dark Blue (22ga) - Cargo light switched ground
Yellow (22ga) - Courtesy Lamp driver in OH Console
Yellow / Black (18ga) - Day brightness sense in Instrument Cluster
White (22ga) - Dome light switch sense in CTM(Central Timer Module)
Pink / Light Blue (22ga) - Courtesy lamp switch output in CTM
Pink / Red (16ga)- Battery Power form PDC (Power distribution Center (20A Fused)
Tan (22ga) - Key in ignition
Light Blue (22ga) - Key in ignition
Black / Yellow (16ga) - Park Lights
Tan (18ga) - Assorted Dash/Console lights (dimmer)

Based on this drawing, the Violet / White wire should be the Low Beam ground line that is wired to the multifunction switch, which should get it's ground from the Light Green wire from the headlight switch.

:4-dontknow: With the way the wiring was altered at the headlight switch, I have to wonder what was done at/near the multifunction switch. These 2 switches need to be in harmony with each other for the system(s) to work.

I hope RamTech can shed some light on this in the morning. A known correct wiring diagram, would be a real asset in this circumstance. We're not just trying to find the problem, but trying to get it back to stock to see if a problem exists! :Wow1:

Brad12kx, since I replaced the multi switch and thought that was the problem and I bought a new headlight switch last night but everything was the same so it wasnt the switches at all, the only wire tampered with was that green one on the back of the headlight switch on the dash and I now have that corrected. I checked the wiring under the dash as I had all the covers off ( and replaced the stereo while I was in the dash ) so now the issue lies under the hood, I noticed the bottom of the distribution center is not on properly but it was dark out and the worklight is only so good so I will probly tear into it again this weekend so I have all day to tinker with it and if you are close by, heck I would enjoy the company trying to figure this out... its a PITA trying to tinker and run up to look at the lights to see whats working or not...lol
Also, when I hit that "wire" they spliced into the purple/white wire I can hear a clicking in the distribution box so it is tripping a relay in there but I pulled one at a time and could still hear ir and feel it so I think it is under that box where the problem lies? Well for now it works enough to get it to pass a legal inspection and I guess I got 50% of the problem fixed, 50% to continue on...lol

That being the case, I'll place my bet on the Orange / Red wire from the right headlight to the power distribution. The connectors on the bottom of the PDC would likely benefit from a good re-seating as well. :smileup:
