Auto Ac

[stingragtiger]

2005 silverado crewcab with auto ac controls. shows fan running but will not work. Does this sound like the blower control module.

I would work from time to time but now it won't work at all. Best place to buy?? Thanks

Replaced the blower control module and all is well. The aluminum heatsink was not making good contact with the circuit board causing it to not work when hot. Worked fine in the cool morning.
