The A/C blower on my 2008 F-250 is working intermittently. When I start my truck the blower may work or not. It works when it wants to. I don't know if it's a relay switch or what. Help!

 

mine does the same things since the day I bought the truck. Under warranty they replaced the ac controls in the truck 3 times. I believe mine has the EATC

My problem is I could be driving and it shuts off. If I restart truck it works again. Luckily now it does not happen that often b/c truck out of warranty

Some have suggested a loose relay under hood.

 

I have the same problem....sometimes I start the truck and the blower works, sometimes not, but not long after I head out on the road, the blower will start working. Have you discovered what your problem was? I have the same truck by the way.

Thanks, Mark
