Question about 2001 Chevrolet Silverado

1 Answer

I have a 2001 Chevy Suburban 4wd, went to Jiffy Lube had oil change, fuel filter and cooling system flush. After the work was done I noticed I had only cool air coming out of the vents. I went back to Jiffy Lube and after a quick inspection, they determinded it was the door blend actuator, the assitant manager wiggle it and warm air started to come out of the vents, but after a few miles cool air started to come out again. My question is, is this the cause of a faulty actuator or something else? If it is the actuator is it something an average guy can replace? Thank you in advance for your reply.

Pulling the dash out to expose the blend door isn't easy. Check for a cracked or missing vacuum hose on the intake manifold.

SOURCE: 1999 Suburban, A/C on warm air from front vents, cold air in rear

The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.

2006 Cadillac cts is burning gas faster than the normal rate after i got an oil change at jiffy lube 2 weeks ago

I dont think there is a connection between an oil change and the gallons per mile.
With that age car, I suggest a Terra engine clean. It will blow away nine years of gunk from the spark plugs, fuel injectors, cylinders and exhaust. Should give you more power, more miles..

Engine Flush.

I get ask this question a lot. Should I do an engine flush? The answer to that is NO! If you have your vehicle serviced at a quick change lube, they will push services like this to you, especially if your a woman. Jiffy Lube is notorious for doing this. Every automotive manufacturer will state in their warranty, if you do this, they will void the warranty simply because it will cause a major engine failure. Over time sludge and deposits build up in an engine, when you flush it, it breaks up these deposits and they settle in the oil pan. Even when you drain the oil and place a new oil filter on, some of these broken up deposits remain in the engine plugging up the oil lube ports. This stops oil from properly lubing vital parts inside the engine causing engine failure. Products like engine flush are known as snake oils in the automotive repair business. The best and safe way to stop sludge build up or remove it, is to use a good quality synthetic oil and quality oil filter. This will end your sludge problem over time. One more thing, avoid quick change lube centers, any of them no matter if it's EZ- Lube, Jiffy Lube, Wal-Mart and on and on. The people working there are not automotive techs, the have not went to collage or have a degree in automotive technology. No one with a degree in automotive technology is going to be working at a quick lube center for minimum wage, they will be working in a good independent service center or dealership making $22 or more per hour. For more information on this, go to youtube and search Jiffy Lube Scam. There are tons of news story video's on all of these centers.

Alright I'm some what ignorant when it comes to cars. I have a 99 chevy blazer 4wd power everything. My heat works fine and dandy. My AC on the other is not cold. It's warm. I also get some weird...

Sounds like you have a dying blower motor. That explains the whining in the dash.But if it's not cooling, bring it back to jiffy lube and ask why. have them show you that the compresser is operating, and that the lines are cold. If this is the case, then it can be a problem inside the dash, blend doors and all.Doubt if jiffy lube can help you there. You'll need a real mechanic. The Jiffy folks should have ethically discussed this with you when they took your cash.At my shop, if it doesn't work when we're done,we discuss it with you. Probably why I'm small and broke, and Jiffy lube is huge and rich! Good luck.

During an oil change at jiffy lube, the car drove in fine, but once the oil change was done the car wouldn't start. The engine would turn over and it looked like the engine was shaking around a lot. They...

Many times when oil appears in your air intake and in the air filter this is usually caused by a plugged pcv valve Positive crankcase ventilation valve it costs anywhere from 3-10 dollars.As far as it not starting my guess is they checked the air filter and left a vacuum hose or airbox open.Some of these vehicle will barely run if an air leak is present at the airbox containing the air filter.Would double check for any vacuum lines that may have been disconnected around the air box and that the box is shut and sealed properly.

What all regular maintance need to be done at 100,000 miles?

Change oil,replace spark plugs and fuel filter,air filter,check all brakes and lube caliper slides,check and flush cooling system,replace trans filter and gasket and perform a trans flush.This will replace all the trans fluid not just the fluid in the trans pan.Add fuel injector cleaner about every oil change.This will keep this vehicle going for another 100k.This is the best engine G.M. has had and will go over 300k.The biggest problem was the upper intake plenum gasket leaking coolant into the cylinders and oil system.Hope this has helped and good luck.

Sensors went bad, at 60 k miles, is this covered in warranty

you need to take the vehicle to a real mechanic. Jiffy lube employes are not mechanics. Change your oil at jiffy lube and get mechanical work done at a reputable auto dealer or mechanic shop.

This happened on mine too. Your tranny is over heating, and needs to cool down before moving on. Pull over to the side of the road in a safe place, and let it idle in nuetural until it cools down, the light will go out then. In mine, it was because my tranny was going out. Have it checked by a tranny shop asap, I went through 5 tranny's in my 98 2500 because they were weak from the factory.

Cause for overheating can be a number of things, old oil, no circulation through radiator, plugged cooling core, filter plugged, if you just had the oil and filter changed they may have put the wrong filter in, and or flushed some particles loose to plug stuff up. Jiffy Lube did that to mine, that's when mine first went out. They made it right, but what a hassle.
