Need a bit of help here, I've got no heat on the drivers side of the car. What do you start with the control module?
If it is how do I get to it without busting everything are there any trick or special tools needed to get to it.

Thanks

Mike, check first and see if you have any door movement codes, these will be 'B' codes. Once you check, then it will be easier to narrow it down, my problem earlier was with the passenger side not giving any heat, I was able to narrow it down to a actuator motor.

I think caddyshack is right. Most likely the actuator. You should be able to access one by removing the glove box and the other from underneath, after you remove the hush panel. I forget which is for the drivers side. Just watch them as someone runs the temp up and down and it will be apparent which one is not operating. If that is not the problem, then try flushing the heater core.
