Well all, still fussing with my heating/AC system. I swear that if it was not for the Cummins engine I would sell this truck immediately due to the "time after time after time" hassles we have been having with the climate control.Back in June or so I took it to a good shop here in town and they pulled the dash and installed a new diverter door coupling. Seems that the coupling had broken and the motor could not move the door. It worked for a few days then stopped but luckily for me it stuck in the cold position so the A/C worked fine and in Arizona in the summer thats important. Finally this fall I took the truck back to have them fix it right.Well kids, the truck has been in the shop 3 times now and it still is not IMHO working right. Second time they found something else wrong and third time they found the diverter door moving but "sticking in the frame" so they shimmed it to work.Now I am able to turn the heater control from cold to hot and the door does move changing the temp but its not right. In my feeble mind when you take it from cold to the 1/3rd position you should get air warmer than full cold. Take it to the 1/2 position and it should be halfway warm. 3/4rds position and it should be pretty warm but not full hot. This is not what happens as it is right now. Now you take it to the 1/2 position and you get either full cold or full hot. Turn it one notch left (cold) and you get full cold, or turn it one click hot and you get full hot. The door is still moving but there is no moderation, its either full hot or cold. They tell me that if the last "shimming" operation did not fix it that we have to replace the diverter door assy AND the housing that its in. That the housing where it mounts is getting old and the door is not moving correctly. Anyone else have this happen? Now to make it worse they say that this part may be NLA, no longer available from Dodge so that they cannot fix it. They will not use anything but dealer sold parts and they say that a 2002 is not supported by Dodge any longer. They are doing all this work for free once I paid for the first repair, so this is why they keep getting it back but am tired of the 20 mile drive each way and hassle with the truck.Would sure appreciate any tips or ideas? Thx,Joe
When working on removing the blend door motor make sure the temp control is in the centered position or it will loose its indexing. This is a site I found a while ago with a cure for broke blend door. It has good info also. They say that you can open up the motor and recalibrate/reindex it if it has rotated out of spec they will include info on how to do it in the directions of the parts to fix the door. http://www.heatertreater.net/Dodge%20Ram%2095-02.htm
