Need help on a/c control
Hello everyone,
I'm new to this forum so please bear with me. I have a 2003 Astro van LT, and it runs great, but I have a problem with heating and a/c controls. It blows hot or cold as it should on low and medium speeds but when I turn it to high it stops blowing all together. Could use some help
thanks

be careful here. The high speed control bypasses the thermal resisters with a relay to supply 12vdc directly to the fan motor. The relay is in the same pack as the thermal resistors. All controlled by the fan speed switch.

Thanks for all your insight guys. Yes the blower does work on all speeds but "high". I am familiar with the resister in this case, as I have replaced it about three years ago. I had to do the modifications to make it fit. I didn't think it would go bad in just three years. I'm going to go ahead and replace it this weekend. Again, thanks for all your help.
