rossg Posted July 28, 2008 Report Share Posted July 28, 2008 I have looked at the posts but I need some help with this. I have a 94 cutlass convertible with climate control. On a recent trip I noticed the car would not blow heat. the a.c. blows ice cold but the heater door does not open to get heat from the heater core. I pulled the motor On the door pulled it apart and checked the motor the motor works but I don't know if the board on the motor is ok. I have come across posts about soldering pins on the controler but there is no pics. Thats fine but i don't know what pins to solder. I am looking for pics or links to wireing diagrams diagnostics any thing to help me solve this problem. I just changed the t stat and I know heat will come out if you open the door manualy. So the problem is in the motor or controler. Quote Link to comment Share on other sites More sharing options...

rossg Posted July 28, 2008 Author Report Share Posted July 28, 2008 well dash is apart don't want to drive car till I figure out whats going on and no 1 has responded to the first post. so I figured posting it somewhere else wouldn't hurt.

Brian P Posted July 28, 2008 Report Share Posted July 28, 2008 I'd have to check what kind of signal the controller sends to the motor but that would be the first thing to check. Both the automatic climate control AND the motor are susceptible to this kind of failure. I'll try to get a wiring diagram posted tonight.

cutlassman Posted December 9, 2008 Report Share Posted December 9, 2008 Don't know if you ever fixed the problem, but the same thing happened on my '92 Cutlass Convertible. I had to replace the Electronic Climate Control unit. I replaced the actuator as well, but the problem was with the main ECC unit. Typical problem.
