2000 GMC Yukon XL Questions & Answers
Hello, I have a 2000
Sounds like a bad blend door actuator. That's the motor that diverts air between the heater core and AC
5.3 L Yukon XL oil pressure problems
Well first the GM oil pressure sending units are notorious for false readings, so what you must do is remove the oil pressure sending unit and plug in a test mechanical gage to verify the engine has acceptable oil pressure, after you are certain the pressure is ok replace the sending unit, it requires a special socket to remove it, the socket is about $5.00 USD. There is a deep socket and a shallow, so check the sending unit for the correct socket fit.
2000 Yukon XL not blowing hot air and overheating
The two symptoms are probably connected...
There are a number of possible conditions that could cause both symptoms and the possibility two unrelated faults have coincidentally caused them should not be ignored. The possibilities should be carefully checked by a competent person to ensure the cure is no more expensive than it needs to be.
It is possible the cause is a defective cylinder head gasket leaking more combustion gas into the cooling system than the degassing system can cope with or the degassing system itself is defective. It is also possible it is a simple leak and a low coolant level.
How to replace the ac compressor clutch on a 2000 gmc yukon xl?
the clutch removal is easy, remove the nut on the front and remove the pressure plate, then remove the retaining clip around the bearing support and pull off the clutch,
it is hard to find a new cllutch, most companies just want to sell you a new compressor. if you need a new one, check
http://www.rockauto.com/ first, then search amazon and ebay for the part number at rock auto, sometimes you can find one less expensive than rock auto but overall rock has the best deals

Lots of power, dash lights up but no ignition power to starter, relay changed, neutral start switch changed, fuses good.
Well, looking at the schematic, there is the IGN A (Fuse 6) in the under-hood fuse block feeding power to both the ignition switch and to the NO contact of the starter relay. Turning the ignition switch to the START position sends this voltage thru the CRANK (Fuse 8) in the instrument panel fuse block and thru the PARK/NEUTRAL position switch, thru the starter relay coil to ground. This should activate the Starter relay and pass voltage to the starter solenoid to ground, activating it. One the starter solenoid activates, batter power is sent to the starter motor, activating it. If, as you say, the fuses are good, the starter relay was replaced and is good, and the Park/Neutral position switch was replaced and is good, then then only items left are the ignition switch itself, the starter solenoid/motor, or the wiring of the circuit.
After Market Radio Installation
Hey man, you have an amplified system. use a 70-1858 wiring harness and jump the blue/white wire from the aftermarket radio to the pink wire on the second plug. this will power on the factory amp with the aftermarket radio.

Why does my 2000 Yukon cut out while I"m driving?
I guess you mean engine dies? You need to determine if the issue is fuel or spark. If spark, it will die flat, fuel often will sputter as it dies. If you can hook up fuel pressure gauge so that you can see it while driving this might help. If you think it is spark issue, check coil and ignition module, crank/cam sensor. Is this random or is there some pattern, such as amount of time driven?
