QUESTION: Symptom:  No heat.

I removed the old blend door actuator and installed a new, turned the temp control knob and observed the gear moving.  I thought, great !!  I've found the problem.  However, now, the new blend door actuator is no longer rotating when I move the temp control knob.  What else could it be?  I get heat now by moving the actuator cam by hand.

I put in a new control unit about a year ago because the mode was haywire and swapped out the current control with one from another Stratus.

ANSWER: Hi Joe,
I would check to see if the door is rotating easily or might instead be binding up mechanically. You could also verify the wiring of the 5 wires. Let me know if you have a volt-ohm meter and can give you the connections.

QUESTION: I do have a volt-ohm meter and was thinking if I had the wiring diagram I could check the voltage or resistance levels at the outputs.

I would appreciate if you could send the wiring information.

ANSWER: I can attach the wiring diagram to an email which I will send to you directly. To do that you must tell me your email address as I don't see it routinely via the Allexpert procedure. So send one more follow-up question only this time click on the box to make it PRIVATE and then in the question box area state what is your email address.

QUESTION: Thanks, my email is  

Answer
Joe,
As you can see,  
that email address didn't get through to me because it was not a PRIVATE question.  So on Friday morning, when I will be available, ask a New question and make that Private and then I will have your address to send the wiring diagrams attached to in an email.
