Heater problems
 

Hey guys, Im lost when it comes to this 99 trailblazer. All fuses are good yet nothing with the automatic climate control works, blower doesnt come on, blend door doesnt cycle. It used to just blow hot air at all times and you could hear the blend door motor cycle and make noises.... Now nothing.

Ive done some research and it seems to be a common problem with the blend door gear breaking.

So is the climate control toast? or do I have other issues?

Also, this blazer is a canadian one if that matter.... LOL

Guess I will continue googling the problem.....

you have to wait 24 hours before you bump a post, you waited 5 days.... with so many active members, it could have just gotten lost in a short amount of time.
i would try this out and see where it gets you. not to pass your problem on, but i think that this has been covered before and you might find a solution. so just give it a quick read through and it might give you an idea, or at least a place to start and then come back and update us on your situation. best of luck buddy.

if you look in the how to / tech section there is info on the climate systems
