Put a new fuel filter in it and primed it...working fine and now problems...put the new EGR valve in it afterwards. First problem I have had with it mechanically since I bought it...
#341 of 365 a/c heater control
Oct 01, 2011 (9:49 pm)
I am experiencing a problem with the a/c and heater controls on my 2004 GMC Sierra 3500. I have the dual zoned a/c heater control system. The driver's side of the system, when set on cold running the a/c will all of a sudden switch to hot air blowing thru the vents, but only on the driver's side. The passenger's side continues to blow cold air. No matter what I do, slide the temp control up and down, turn off the fan control, or switch the vent control to a different setting, the hot air continues to blow. The only way to make it go back to the a/c mode is to turn off the ignition and then restart the truck (very inconvenient when driving down the road). Sometimes this will happen often, then other times it will act normal for weeks without incident. Any ideas?

my truck did the same thing, and last week it went in for a new fan speed switch under a recall. Has not done it since. Check with dealer to see if your truck is part of the recall.

My 06 now has a ticking sound in the engine, plus it's cutting back and shaking like crazy

i have an 04 3500 crew dually 4x4, 6.6L Duramax 180,000miles, all stock except the aluminum wheels. I am getting 23mpg open highway and 16mpg in town heavy traffic. My best fuel mileage open highway is 71ish mph... if I run 55-65 the mpg drops off. I typically drive 500+ miles per week for work so this one NEVER sits around idle, that might be the secret?
