Question about 1996 GMC Yukon
2006 GMC Yukon 4x4 (not the Denali) A/C fan cuts out completely at specific times. I have a digital display with automatic ability. The fan works properly when I have it set to A/C with any fan setting (even high). However when I have it set to high fan AND then turn on "recirculate" the fan cuts out entirely after a few seconds of working. There is absolutely no air flow for about 5 seconds then the fan comes back on with lots of speed and cuts out after a few seconds again. This will happen over and over again. The digital display does not change from its initial settings, the engine light does not come on nor do any other lights come on or go off. I have also found this same problem with defrost on high fan. HELP!
Replay the blower resistor. Used to be you could replace the relay, but they are built into the resistor now. Should be under the passenger side dash. Usually behind the blower. There will be four to six small wires going to it and two big wires coming from it going to the blower motor.

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

Call your local GMC Dealer and see if they have the climate control panel in stock. What happens is the circuit board on the back of the panel shorts out. The panel comes as an assembly and is very easy to replace. Don't go with a wrecking yard piece. I made that mistake once and it didn't work either. I got one from the Chevy dealer and it worked perfectly.

I thought I had same problem . . . . until you turn the overhead switch completely to the right which I believe actually trips it to heat mode. hope this helps. Then back to the left copletely for air.

The switch or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Sierra running 100% again soon.
