2005 GMC Envoy - Page 7 - Answered Questions & Fixed issues

1st, is the check engine light on?...How many miles on he vehicle? I would suspect the throttle position sensor (TPS) . Also, the mass air flow sensor (MAS)....Or,it could be you just need new spark plugs and, or, wires....

The first thing I would do is check the fuses. The fuse/circuit for the power windows would require more amperage than the mirror or locks and, would therefore, be on a totally different circuit. Check the owners manual for the location of the fuse. Was the window acting up (operating slowly or making mechanical noises or grinding noises) if any of these were noticed, I would suspect a faulty motor or broken window regulator. Me thinks, if it is anything more than a blown fuse, it would be beyond your skill level to fix therefore, I would take it to a reputable repair facility and ask them to check it out. If it is a fuse it would be a minimal charge.

Did you change the fuel filter as well?

877-265-3278 - Is the number I was given for Citizens Auto Finance. RBS Citizens is the name they go by I was told. I also was told, 800-922-9999.

There is no cabin filter

First you have to determine if it is a fuel delivery problem or a spark problem. Have you checked if there are any codes stored?

No there is no common fuse, but the Liftgate Module controls both of these functions. Check fuse #3 in the rear fuse box.

you may also want to check the idle air control and the mass air control sensor, if not working properly they can cause both symptoms

Check the Mega fuse, it is located in front of the underhood fuse box. It is a large 125A fuse.

Google the question & look on the internet I bet your going to drop the fuel tank, if you have issue with either Better use a professional scan tool & smoke the evap system, to do the proper testing before, you do a hard job for no reason or no testing to find a problem Get the codes then google them

What is the OBDII code

Three inches at a time, or three inches total? If three inches at a time, you need a power window motor. If three inches total, you need a window regulator. Both these items are typically replaced as an assembly anyway.

We had a dodge dakota with the same symptoms and they found a corroded pin on the main connector to the ecm . I think P1682 is low voltage from the charging system. Hope this might help.

Probably your fuel relay. Tricky little buggers but very easy to fix.

You won't believe how simple this is. It's on the driverside in front of the brake booster right there on top, there for the taking. Unplug the electrical connector and pull it out. Literally a 30 second job.

remove radio. take to radio repair shop.

What is your question? I can help you what ever your question is here with this engine. Use only AC Delco brand 41-103, our engines love these. Any other questions?

The are on the engine block. Sometimes the can be behind. On my van I had to take the windshield wiper assembly and reach around the back of the engine to get to them.

usually that sound is associated with a defective clutch fan... did you get the right one for your application... thermal or non thermal did you purchase an after market cheap one... I'd replace it with another one and try again
