AC blower problems
This is my first post on here and I am hoping that I find this forum to as helpful as the corvette and harley forums have been to me.
Here is my issue:
I have a 2004, 2500 4x4, 5.7
About a month ago i started having this problem that once in a while when i started the truck I would get no blowing from the AC. I could feel that there was very cold air trickling out of the duct but no blower. I would turn the truck off, then turn it back on and that would solve the problem.
Friday, it happened and the blower has not come back on since. at first i thought it was a panel switch issue but have since realized that the temp. switch and the blend switch are working.:doh:
So i feel it is now either the blower motor or the blower motor resistor.
How can i test the resistor and can i test the blower motor by simply connecting it straight to 12v and a ground?:4-dontknow:
Any suggestions would be reatly appreciated.
If it is the resistor the motor should still blow on the highest setting.
yeah it might still be the selector swithc in the dash or the motor itself
If there was an issue with the motor you would have heard some noise most of the time ( DC motors are very reliable ) I would guess that the switch went or a lose wire fried. I would check to see if there's a circuit breaker first, they some times go, then work your way from there or the motor on back till you find power. I hate taking apart the dash. BE CAREFUL YOU CAN SET OFF THE AIRBAGS WHEN PROBING.
I have been battling this same issue in my 02 Ram 1500. I have read somewhere that this issue lies within the steering column cover. I have yet to remove this and look under it, but may do it later today. The other issue with mine is that the blower stays on when I turn the truck off. When its on the lowest level, I ussually forget about it and come back to a dead battery the following day.
Good Luck! :LOL:
