Hey guys, I'm new to this forum.
Okay, here's the truck, have an 06 f-250 superduty 6.0, has the fancy push button climate control, fx4, lariat the works.
The problem is, the vents(on the front of the dash, passenger/driver) don't work, and instead, the air is routed up through the defrost vents under the windshield. At first, they wouldn't come back on when the truck was started(when It was previously set), I'd have to turn off the AC, then turn it back on to work. Another condition is when the weather is over 102 it seems to work fine. Now it seems to work when it wants to.
Any ideas on what it could be?
Also, Is the vent control vacuum actuated or is it electronic?
I've got a trip across the desert to AZ and AC would be nice.
Thanks in advance to all who reply
