Over heating/heat on one side of cab only
 
Here is the problem i'm having with my 2002 Dodge RAM 1500 4.7. The truck overheated I then refilled and bled the system and within minutes it boiled over and large amount of antifreeze exited through the over flow. I also have heat on the passenger side only. I took the vehicle to the shop they of course said the system was full of air again and after bleeding it again couldn't get it to over heat. Thermostat was replaced still no heat on drivers side and engine seems to be running hotter then before anyone else with this problem that can possibly help me..Thanks

the heat on one side of the truck is a separate problem from the over heating. you sure you put the same thermostat temp range in?

Not sure about the thermostat temp range repair shop replaced it that would explain the higher temp range thanks.. Also after bleeding the system before it over heated the second time i had heat on both sides of truck not sure if the heater core is the culprit because the problem stared after i started using heat.

heater controls
 
I have a 2005 dodge ram 1500 Laramie just wondering if anyone has ever had a problem with heater controls when I put my selector on my feet it comes out powerful up on the windshield and a little bit from the floor when I put the selector just on the windshield it blows on the windshield and little bit on the floor and when I turn it to any other selection it works fine

I think issue is resolved
 
I believe the issue has been resolved. The small hose that runs from the top of the radiator was blocked from debris. I cleared the line and bled the system again and now engine is not overheating and heat has returned to the cab( I believe this blockage caused the heater core to become air bound) My next move now is to flush the whole system individually to clear anything that may still be in the system.

I have that same issue on my 05' from what I have just learned tonight, it's your Mode 2 door. From the videos I just watched, it does not look very easy either to fix...even though im going to try lol.

I removed my lower dash and made sure all my zone doors were operating properly and I have sufficient air flow moving through the system. My problem is that I do not get hot air through the dash vents or the floor vent on the drivers side only. Heat is good on the passenger side. Any suggestions?

I just discovered today that I have the same issue as jonny68, with the driver's side of the cab not getting any heat. I am on the road and in really cold weather so I would like to resolve this asap. I will take a look at the small hose that runs from the top of the radiator tomorrow, but it is too cold and dark to look right now. The only thing I can think of that I have done recently is I caulked around the top of the coolant reserve tank because it was leaking pretty bad. Also my hood slammed shut the other day with a couple tools inside (who designs a hood without a lock of some sort anyway?). I looked for any damage but I didn't notice anything.

I just checked this morning and my coolant reserve tank is still leaking despite my fix. Do you think the radiator isn't getting enough coolant? My truck wasn't overheating but it was also never warmer than 10 degrees all day yesterday.

Its going to be your mode 2 door. which is barried underneath your dash, a lot of screws, and a metal plate that you may need to cut to change the door.
I just about took apart my whole dash, when i decided it was not a winter job and I would just deal with it lol.

I did mess with the mode 2 door motor and linkage and it seemed to have made a diff. I do have heat to my side now, but I only get heat on full fan, so maybe if you have a garage or somewhere warm to tackle it, you might be able to do the same thing. i'd rather adjust the temp then not have heat at all, or crack a window (i'm a smoker so thats usually happening anyways lol)

there is a few other threads on this. one has links to videos on what to do for where you godda start to tear apart the dash. i'll try to remember to post them here for you to look at :)
