Question Answered: Battery Meter goes down. It even turns off the car.
December 26, 2008, 10:15 AM
It sounds like the engine idle may be to low on your Yukon. There could be deposits built up behind the throttle plate which will restrict the air flow at idle. The fix would be to clean the throttle body area with carburetor cleaner and wipe it out with a clean shop rag. There may also be a software update available from GM which will help the computer compensate to the build-up of future deposits in the throttle body. The check engine (SES) light may be on after cleaning the throttle body and the code set will need to be cleared to turn off the light.
Question Answered: serpentine belt falling off
December 26, 2008, 10:08 AM
The serpentine belt may come off due to a worn tensioner, idler pulley or pulley alignment. You should have a qualified technician look at the belt alignment while the engine is running. Anything that looks out of alignment at that point should be repaired. If everything looks ok the fault could be with the tensioner or idler pulley. You may need to replace the tensioner, idler pulley, and the serpentine belt to correct the problem.
Question Answered: Oil Pan Made out of What
December 19, 2008, 11:00 AM
An easy way the tell if your oil pan is steel or aluminum is to touch it with a magnet. The magnet will stick to steel but not aluminum. Please make sure you are checking the engine oil pan, not the transmission oil pan!
Question Answered: power steering fluid foams up
December 19, 2008, 10:53 AM
Foam in the power steering is caused by air in the system. A problem with the steering rack or the pump could cause air to enter the system. A restriction some where in the power steering system could cause the fluid to overheat and expand. The expanding fluid will be forced out of the reservoir. You may need to have your power steering system checked by a repair shop to try and confirm the cause of the fault.
Question Answered: oil leak
December 19, 2008, 10:38 AM
Oil leaks can be very hard to pin point. When replacing the filter always make sure the gasket from the old filter is not stuck on the mounting surface. Two oil filter gaskets will always cause a leak. If the leak is from behind the filter it could be related to the oil filter mounting adapter or the oil cooler lines attached to it if so equipped. You may need help from a qualified technician to help you isolate the cause of the oil leak.
Question Answered: brake light
December 19, 2008, 10:31 AM
Low brake fluid in the master cylinder reservoir can cause the brake light to come on when turning, try checking the fluid level. The steering wheel wobble could be caused by loose front suspension components, loose steering column components, or a wheel/tire problem. This sounds like a safety issue and you should have the problem checked by a qualified technician as soon as possible!
Question Answered: 91 explorer, no reverse and leaking fluid
December 19, 2008, 10:23 AM
Overheating of the transmission fluid will cause it to expand and be pushed out of the overflow tube. If the transmission was a bit overfull to start with that will worsen the problem. The loss of reverse may have caused the transmission to slip and the fluid to overheat. No mater what the outside temperature is a slipping transmission can overheat the internal fluid. The transmission fluid cooler should also be checked for proper operation.
Question Answered: how to put a heating valve on ?
December 19, 2008, 10:12 AM
I cannot say from my end if you have put the heater control valve on correctly or not. The best way for you to find out would be to get a repair manual for your van. That would also help you to isolate the cause of your lack of heat issue. In order for the heater to provide heat you must have correct coolant flow through the heater core and proper operation of the temperature control door inside the heater/air conditioning air box.
Question Answered: Poor Heating
December 19, 2008, 10:04 AM
There could be a problem with poor coolant flow at idle, poor heater blower motor operation, or a fault with the temperature control function of the heating/air conditioning system. You may need a shop manual for you vehicle to help you isolate the problem.
Question Answered: Right front window stuck in up position
December 19, 2008, 09:59 AM
Here is a quick test: With the key on, hold the window switch for the affected door in the down position and open and close the door firmly a few times. If the window starts working the fault is most likely with the window motor. If nothing happens, the next step would be to remove the door panel and perform some basic electrical diagnosis to isolate the fault.
Problem Reported: Engine Starts and Stalls Due to Secutiry System Fault
January 14, 2011, 10:10 AM

The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.

Car Review: 2005 GMC Envoy

The smooth running V6 makes this SUV, and Lots of power. The ride is also good. Only a few minor problems. This truck just runs and runs.
Car Review: 2001 Pontiac Grand Prix
November 03, 2008, 02:32 PM
My Grand Prix is not a bad driving car. Power is good and it handles well. I had a problem with the intake manifold leaking coolant and don't spill coffee or soda on the shifter. It will become sticky and hard to shift out of park. The shifter will need to be removed and cleaned to correct the problem.
Car Review: 2002 Pontiac Firebird
November 03, 2008, 02:21 PM
I think we need a bit more information from "natural energy"! Top fuel mileage from my V8 Bird has been in the mid 20'S. Lot's of squeeks and rattels. The drivers side window motor had to be replaced. Over all, not a bad car - better for a smaller person!
Car Review: 2003 Cadillac Escalade
November 03, 2008, 02:12 PM
My Escalade has held up fairly well. The speedometer has faled and needed to be repaired. The fuel pump has failed and needed to be replaced. The oversize tires tend to look nice but ride hard, I am glad gas has come down a bit - the Excalade will burn some fuel to get from here tho there!
Car Review: 1996 Pontiac Grand Am
October 10, 2008, 03:47 PM
Good basic car. May have problems with coolant leaks from the engine. Interior trim and seats will show signs of wear sooner than expected. The front brakes may pulsate when stoping caused by worn rotors. Just keep up with the minor repairs and you may be able to avoid some of the major ones.
Car Review: 1998 Pontiac Bonneville
October 10, 2008, 03:34 PM
The Bonneville has held together quite well. The intake may leak causing the engine not to run but after that is taken care of the engine performs quite well. If you like the looks, this may be the car for you.
Car Review: 1994 GMC Sonoma
October 10, 2008, 03:19 PM
My 4wd Sonoma has been an excelent truck. The engine has a bit of a rough idle (from new) but runs strong and gets OK gas mileage. Front brakes wear out on the early side and now I have developed a noise in the front end, maybe worn control arm bushings. The only major repair has been a fuel pump replacement at 70k.
Car Review: 2004 Chevrolet Trailblazer
October 10, 2008, 03:13 PM
The inline 6 cylinder engine in this Trailblazer is one of the best engines from GM in years. Combine this fine engine with a smooth shifting automatic transmission and you end up with a fine running midsize SUV. Seating is confortable for 4 adults and is capable of handling most hauling needs. GM seems to have worked out the minor electrical issues that showed up on some of the early models.
Car Review: 2002 Chevrolet Tahoe
October 03, 2008, 02:12 PM
Don't drive with the parking brake on by mistake, even for a short time or the parking brake shoes will need to be replaced. one other major proplem area is the fuel pump - it may leave you stranded! Very nice vechile otherwise. You can carry or tow just about anything.
Car Review: 2000 Cadillac DeVille
October 03, 2008, 01:50 PM
The Deville is a great car when it runs! Problem areas center around overheating, oil leaks, and ignition system faults. Overheating can be a real issue leading to blown headgaskets. Many of my friends have traded their Devilles in whe the problems get out of hand.
