QuestionWe have the fancier digital auto temp unit. Also, the blower works, but the air is cool or cold coming out.-------------------------
Followup To Question -
I know this out of your date range but...
2002 T&C Van.
#1 The heater just stopped blowing warm air today. What can I look for before I take it into service?
#2 The interior lights occasionally come on and go off while driving. We had the dealership look into it, but they found nothing. Any thoughts?

Hi Bret,
On the heater question, do you mean the air blows but it isn't warm (internal door in the heater not positioned to send the incoming air over the heater core) or that the air doesn't blow at all (fan problem...Fuse?) If the former, then you would want to check out the cable that connects the temp lever to the internal control door. If the lever feels really loose then the cable probably is detached or broken. You would have to remove the bezels around the center console and then remove the heater control unit and study how the cable is connected to the control lever and to the door lever in the cabinet of the unit. If you have the fancier automatic temperature control unit with the digital display there is likely to be self-test you can perform and get a fault code readout that tells what is wrong. Let me know and I'll send you back that test. Or you
get the procedure at www.allpar.com and look up the ATC repair page.

AnswerHi Bret,
Thanks for the clarification. Unfortunately I don't have a manual for the more recent version of the ATC (the earlier one has a different set of fault code #'s but they may overlap in their explanations, we shall see) so I have here the reference that I mentioned in my first answer:
http://www.allpar.com/fix/codes-climate.html
So take a look at that and try the self-diagnostic readout for fault codes with your ATC and then let me know if something useful came out, but what it might mean would be the "fix" is still unclear to you.
On the interior lights, I suspect that one of the door push button switches is out of adjustment to the striker surface that turns the lights off when you close the door. So I would try each of the doors that can cause the lights to go 'on' and find the one that requires the least amount of ajar position to turn on the lights. That one is probably the one that will come 'on' by itself due to road vibration and body flexing when you are in motion. You could try to add a little bit of metal (say expoxy a penny to the striking surface of the switch, or shim the switch out toward the striking surface) to correct this annoyance. It could also be that adjusting the door latch stiker plate at the frame so that the door closes more tightly will correct the problem without the need to fiddle with adding metal or adjusting the push button.
