Dodge Repair Questions? Ask a Mechanic for Answers ASAP
I have a 2002 Dodge Ram and it has started blowing cold air only on the driver side and warm air on the passenger side. Then, while driving down the road it will go from blowing cold air and then just start blowing hot air out all vents. Also, the air is not blowing very hard out the vents, although the fan sounds like it is running full speed. I tried looking up information and decided it was probably the blend door. I took the dash out and could see that the recirculating door works and I know the mode door works because I can isolate the air to windshield, feet and vents. That leaves the blend door. I took the actuator off and moved the blend doors with my hands. They felt good. I put the actuator back on and turned from hot to cold and was able to watch the actuator rotate the rods that close and open the doors. I cannot physically see the doors close because I can't figure out how to get to them. If they open and close what else could it be? Although it seems to produce cold air, I still went ahead and checked the refrigerant pressure and it seems to be good. So it's got to be a problem on the inside. Suggestions?
I apologize for the delay, but I have been tied up on other things and have not had a chance to follow up on the questions above. I will get back to you as soon as I get a chance to get back to the truck.
