I've never had a problem with my a/c until I picked it up from the repair shop this past week. My 2005 Yukon has the Auto Tri-Zone A/C & Heat feature. I took it into dealership to have the 3-2 solenoid they said the hole casing/harness had to be replaced in the transmission which I don't know about but anyway I had them replace the filter. My Yukon has 105000 miles on it. I didn't want them to replace the fluid because nothing was wrong with it and I thought it would cause more problems so they took half out so they could do the repair and then refilled and that was all. Now the front A/c in my Yukon does not function right. the back works just as it always has and it very cold and is working properly. When the front does work it works at all levels (can be turned high and low speed) and is very cold as usual but doesn't always turn on and once the driver side vent didn't work but all other vents worked. when it does eventually decide to work as I'm driving in the 100 degree weather it comes on full blast on auto and I can then turn it down and direct the air flow from auto to blow through the vents and the floor board vents as well. When I called to let the dealership know that they needed to fix the a/c that they must have hit something they told me it would cost me 300 for them to look at it and could cost additional in parts and labor to fix. I was floored. Can someone please tell me if this was just a bad timing for me or did the repair shop do this? I kind of feel as though I'm getting overcharged but if not then I'm willing to pay. I just forked out $800 for the 3-2 solenoid and filter replacement.

The oil level is always full but the oil pressure gauge is always fluctuating between 20 and 40. None of the dash lights are on. So I don't know what to do. The tapping sounds a bomb ticking.

My truck won't take gas. Replaced canister purge valve, solenoid under hood near intake & fuel cap, finally took to shop & they replaced fuel vapor canister & blew out all the lines. Still NOTHING after all of that.
The fuel tank pressure sensor above the gas tank has not been replaced as of yet.
Any input? What good is his "New state of the art diagnostic station"???

There is a unit under the front dash that is ticking when the air conditioner or air circulation is on. Sometimes it causes just heat to come out. What is that part so I can replace it or has it been recalled?

The lift gate door acuator no longer is working. My rear door does not lock. Has it been recalled? If not, how much is the part to replace?

Rear buttons won't work

Two weeks ago the DVD player mounted to the headliner quit working. Today my master control for the defrost, front driver and passenger heater isn't working. It works but the heater isn't blowing. And when I purchased the vehicle the drivers heated seat option only stays on for a split second. What could be the underlying cause be, and what should I be looking for? No codes are showing... and that port too was not working neither until a fuse was replaced. All other fuses ARE GOOD.

All other volumes work fine, it's just volume 4 and 5 that don't work on my air conditioner in my 2005 Yukon.
