Anybody had anything like this happen? I was riding down the road and reached down to adjust the AC temp on my 2004 Lariet. AC suddenly went off. Turned on again but would not blow cold air, just hot air. When I arrived home I checked all fuses. When I started the truck the lights on the control panel flashed on and off. I turned the truck off, restarted and it began working again. I'm not sure but it seems like the AC just does not get as cold as it use to but I haven't had it in for the dealer to check yet. Any ideas?

 

I've had one Lariat Supercrew at work do that to me before; the EATC display with constantly flash on and off. The fix was to replace the EATC control head.

Hope that helps.
