the wind broke the visor and all that was left was the brakelight

so I replaced battery in 2 keyless controllers and tried resetting like directions on you tube did not work cannot unlock doors with remote also my rear door does not lock and the wiper does not work either I unlocked rear latch by hand after i did that wiper stopped working at all and the rear back door will not lock even when I lock the doors with the lock switch on driver side door it only locks 2 front doors and 2 rear doors not the rear door

I switch on the car after that turn on the AC , but the air not come out and the compressor switch on.

Could problem be the fuse

Driver seat will go all directions except forward

Recently dash lights come on when we start to drive and the heater stops. We have had the vehicle 3 months and we're getting ready to get a mechanic go thru it.

Got in the car this afternoon and started the engine. After idling for about a minute it shut off. I restarted the engine only to find it idling very hard (it wasn't before). I started to leave the lot and the vehicle seemed to be jerky when trying to accelerate. Shortly after the engine light began to blink. I got the car home (about 2.5 miles) and turned then engine off. At this point I became aware that the blower fan was running on high without the key in the ignition.

Any thoughts are greatly appreciated.

Sorry for the double post, in another thread I posted as my car being a 2005 Trailblazer, my car is a 2004 Envoy. I can't figure out how to delete the other one.

My daughter left a car seat warmer plugged in over night and my battery was dead the next day. I jumped the vehicle and it fires up nice and smooth and sounds like everything is great, but the car runs for about 1 second then shuts off. My key fob will no longer unlock the car or do anything, the locks won't engage or disengage when the button is pressed, the stereo won't turn on.. The dash reads Unknown Driver instead of Driver 1 Driver 2.

I tried the 30 minute reset procedure, but I may have done it wrong, because there is no SECURITY light that flashes or even comes on for that matter. There isn't a Check Engine Light on, or any indication that something is wrong, the car simply starts and shuts off immediately. I have two keys, neither of them work.

So far I have tried to put the ignition in the on position, let it sit for 10 minutes and turn it off for 5 seconds and try to start it. That didn't work, so I tried to do that 3 times over, but one thing was missing from the instructions that I followed: the part where the security light blinks or turns off after 10 minutes.

Also, Does anyone know which anti-theft system this vehicle has?

Had battery replaced now seat controls and mirrors won't work where is the problem

2004 envoy uvx std, this model as roof the moves . The message I have on my dash tells me roof is open.

Using gas like crazy. Also battery goes dead for no reason by the time I get it to the shop no codes..but nothing on just goes dead overnite.bought 2 new batteries. But I need to no were the ECM GOES

Usually when oil pressure is low a white cloud of smoke comes out of the tailpipe when you first start it

The car can be off and the lights will just come back on

If the engine is not turning because I slid on some ice 2wks ago. My vehicle tip on the driver side, I put it back in park n shut if off. Now it won't start, the fan won't turn. It still has power too. The oil level is ok. What can I do to turn the engine so it'll start? It was on one side 30min at the most then we tipped it over.

I parked it shutt it off then ten min went to start but all it dif was click like the battery is dead so charged battery complete nothing same click cluck. I went a grabbed a heavy duty with charge also same click it's very important cause I live way out I need it bad for daughters.. Would it b thestarter by chancey

This has only happened twice. It seems to only happen when I hit speed bumps. After I go over one, I'm not able to steer not accelerate. No engine lights come on or anything. I try to put it in park then back in drive but nothing happens. I have to turn the ignition off to drive normal again.

Seems to get worse at turning... really bad as you turn it up
