2000 GMC Jimmy SLE 4D, 4WD - 2 problems: 1) Sunroof had been stuck ope - got it closed - dealer says that the relay in motor is shot - can i replace relay or need to replace whole motor? Where do I get these? 2) Water leaks in thru driver's window (no rain guards) - has corroded the mirror circuit board - need to replace it, but can't find one...ideas? We can do the repairs ourselves, as hubby is an ex-army mech and is awesome with fixing the vehicles - but cannot seem to find either of these...... thanks so much!!! (we are in Canada, but would be willing to buy in US if we can find the parts)

Looks like you can get a motor assembly at Rockauto for about 180. Not sure if the relay is separate- you should check all relay and fuse boxes for anything related to the sunroof. There is also mention of a relearn procedure that supposedly fixed someone else's issue but I can't find more info on that.
You might try ebay for the circuit board. Also, do some research and see if there are other models that use the same relay (like a Chevy blazer maybe). I doubt that board is only used in your Jimmy. Sharing parts saves them money. So see where else it's usedan and that will broaden your options.

SOURCE: Freeze Plug Leak on my 1996 GMC Jimmy

i would hardly call this repair simple or inexpensive. the part itself yes the labor probably not. i have made this repair myself to my 97 jimmy if you have 4 wheel drive the transfer case up front makes this repair next to impossible from the underside of the car plus the fact that it is behind the motor mount means the the mount must be removed. this involves raising or removing the motor. simple? on a car of this age you will probably find (as i did) the motor mounts are damaged might as well replace them too the parts are fairly inexpensive. also look into replacing all the plugs so you dont have to do this again in a few years. oh yea use the proper antifreeze mix in your radiator water is what rusts out the plugs

Use the Owner's Manual to manually go into neutral and reset to 2WD HI. But then look under the hood check the fuses or look for wiring that may have come unplugged.

SOURCE: how to replace driver side mirror on 1999 GMC

if there is a plastic cover directly behind the mirror on the inside of the car it should come off by gently prying it with a flat blade or screwdriver around the edge of it as most are held on by plastic clips.
Once it is removed it will expose the nuts or bolts that hold the mirror to the door but dont forget to remove the electric wire plug that leads to the mirror

Stuck sunroof

check all fuses. (both fuse boxes)
if they are good.
that it can be 2 problems
1: electrical
2: it mech. jammed. up.
what a tech does, is check for 12v to the motor as you flip the switch
if 12v good the motors bad (silent) or jammed (groans)
if 12v pins , at 0v. then the power feed is bad, (switches and relays) ask how, (voltmeter checks easy)
if 12v to motor, then detach motor drive, and try to move roof
by hand , cant?, then its JAMMED, fix it. (mech. fault ,pure)
if you can move roof easy , then the motor is toast, replace it.

2000 gmc jimmy -4x4 stuck in 4 auto -driverside power window stuck(not the switch i think its the motor) -right side wheel bearing? caused vehicle out of alignment. -code ( secondary air injection...

4wd switch is a push button select, they are known to go bad on occasion. Take switch out of dash is not fun, would suggest taking it to a dealer.

Window motors can be replaced without extensive tools or knowledge. It takes more time to get the door panel off than replace the motor.

Yes, bad wheel bearings will cause aligment problems. They can be replaced at home, you will need to remove the wheel, brake assembly, brake mounting bracket, then the wheel bearing (hub) itself. Does require an 18mm wrench and socket (not common in your tool kit) and a 31mm (Ibelieve) socket for the nut on the end of the drive axle. Impact wrench recommended to remove that nut.
Reverse for assembly. Then have your wheels aligned. Best to replace both sides, (they are a different part # for driver and passenger side) They usually only last 60K to 100K miles.

Hot do i close the sunroof of a Oldsmobile Aurora 2001. I pressed the 1-2-c after that it stucked. We tried pressing the open and close button and it's not working anymore. What is the problem?

Id start by just checking the fuse and relay for the sunroof to make sure they are good. Im not exacly sure, but I think the sunroof fuse and relay are in the fuse box located under your back seat. Your owners manual has a diagram of both the fuse boxes in that car (under the hood to). Id start here. If the fuses and relay is good, I would take it to a dealer, it may be the motor. If you can hear the motor whining but it is just not moving, something may be jammed in the track, Good luck

Repair sunroof that will not open

Sorry but that generally means a gear is stripped. The whole actuator assembly will have to be replaced.

My truck is stuck in 4LO and it won't come out of 4LO.

Likely either a shifter position sensor, transmission position sensor, or a differential position sensor. Had same issue w/ my Montero and it ended up being one of the 5 sensors on the transfer case. It was pretty tough to get to, so replaced all 5. That fixed it.

If you have front end problems like an pitman arm or idle arm needs to be replaced, it may not got into 4 wheel drive. Go to the nearest muffler shop or mechanic to have them lift up your truck to see if something needs to be replaced.
