Question Answered: heater blows cool air does not heat up. All coolant levels are good. What do I
December 07, 2016, 03:44 PM
With the engine at operating temperature, check the heater hoses where they enter the firewall. they should both be hot. If they are not there is a coolant flow problem. IF both are warm to hot that would indicate a temperature blend door issue.
Question Answered: Do later year yukons use different 4wd systems
December 07, 2016, 03:39 PM
I do not believe any Yukons are all wheel drive. All wheel drive is "full time" 4 wheel drive. A 4wd system will allow the option of 2 or 4 wheel drive - All wheel drive will not.

Question Answered: will it run ok with 80 commpression in 2 cilleders

No, 80 PSI compression is not enough for the cylinder to fire. The compression readings for all cylinders in a given engine should be within 10% of each other.
Question Answered: I just had a cooling sensor replaced my mechanic said I have to drive it for so many miles for it to pass inspection why is this
December 02, 2016, 03:22 PM
When fault code are cleared from the PCM history data is cleared as well. Some of this data includes "Monitors", these are tests the PCM runs to help make sure the emission system is operation properly. Driving the car for a few days should allow these tests to run and the "Monitors" to reset.

Problem Reported: Fuel Gauge Needle Stuck on Wrong Side of "Empty Stop"
February 23, 2012, 10:17 AM
<p>Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.</p>

Comment: Floor Mats and Unintended Acceleration
July 10, 2012, 12:02 PM
A well placed strip of heavy duty, self adhesive Velcro on the back of the floor mat may help keep it in position. First check to see if the "loop" side of the Velcro will grab the carpet. If it will, placing a strip on the bottom of the floor mat at the edge near the drivers seat should help.

Comment: True or False: Let Your Car Warm Up Before Driving
April 14, 2011, 08:36 AM
Cpete, When idling or driving a vehicle when cold, condensation will form in the exhaust system. More exhaust flow through the exhaust system while driving a cold vehicle will actually warm the exhaust system faster that if you were to let the engine idle until the exhaust system warmed up.
