Can any help me with step by step instructions on how to remove and replace the Electric window motor and regulator on my 1999 GMC Sierra 1500 series (New Body Style) pickup? This is the motor with the cable type regulator.

Remove the door trim panel. 3. Remove the water deflector. 4. Remove the door speaker. 5. Support the window. 6. Disconnect the wiring harness from the window regulator motor. 7. Remove the 3 bolts (1) from the window motor located on the front side of the motor. IMPORTANT: Do not allow the cable gear to come out of the housing. A failure will result with the cable coming off the spool. 8. Separate the motor from the cable housing by wiggling the window motor. Observe the orientation of the window motor. 9. Remove the motor from the door regulator assembly. Install 1. Install the motor to the cable housing by wiggling it into place. NOTE: Refer to Fastener Notice in Service Precautions. 2. Install the 3 bolts to the window motor. Tighten Tighten the bolts to 5 N.m (44 lb in). 3. Install the window, if removed. 4. Connect the wiring harness to the window regulator motor. 5. Remove the window support. 6. Connect the wire connector to the switch to inspect the operation of the window. After inspection disconnect the wiring harness and continue the installation. 7. Install the speaker. 8. Install the water deflector. 9. Install the door trim panel. |

I have a 2000 Sierra 1500 Std. Cab, Short Bed, 4WD, 40000 Miles. At about 30 to 50MPH there is an apparent "grinding" noise that appears to come from the left front wheel. The "grinding" seems to be in time with the wheel rotation and can be felt through the steering wheel. All symptoms completely dissappear when turning to the left (at speed). All indications are pointing to a failed left front wheel bearing as the cause. The wheel bearing was replaced but the noise is the same. Any ideas out there as to what the source of the problem might be? Ed

Replying to: larryd27 (Aug 19, 2005 7:10 pm) If all that stuff looks right, start looking for a short somewhere. I've had trailer harnesses go bad internally to the plug and cause this sort of thing even though the plug looked fine on the outside. Good luck. - Tim |

I have 2000 Sierra 1500 and the driver's side mirror (OEM) vibrates excessively. I ordered a new one three weeks ago and received and installed it today. It's from CIPA Mirrors. After a test drive I've decided that's it worse than the OEM one I replaced. The passenger side mirror is as solid as a rock. Maybe I just received a bad mirror. Any info is appreciated.

Anyone out there experiencing a clunk, clunk sound like an electric motor hitting a stop in the 2005 GMC Sierra? Mine has less than 4200 miles on it and this sound has surprised me twice in the last two weeks. Other than that the truck is/has been excellent. Even medium towing.

Hi, New Guy Here I just bought a 2000 GMC Ex-Cab 4.8L and already it has been taken back to the dealer twice for repairs all before my first payment! I will tell you what has been done and then let you know my most recent problem. 1. Fuel Gauge Sensor Replaced - 2. PW - Window Regulator - 3. Power Steering Unit and Steering Shaft - 4. Heater Fan - 5. Alignment, Rotate Tires - Now - Has anyone had this problem... In the rear-end, Take off and not only hear a clunk noise, but feel it go through the driveline. Really notice it when taken off at an angle (forward or reverse) such as from a bottom of a hill. For the most part, it when taking off from a stop. The dealer has checked the universal joints, yoke, springs, shocks, u-bolts etc... Dealers response? "This is normal" I know when you shift gears from say, reverse to drive - yes it does make a "normal" noise, but what I am hearing is LOUD. Note; This was not happening when I first bought the truck, maybe 3-4 weeks after. Does anyone else have this problem? Any suggestions? Thanks All

Replying to: dryodt (Aug 25, 2005 7:18 am) I'm not having much luck with mine. I'm almost suspecting body flex at a seam but it's too difficult to diagnose unless I got a little guy to ride underneath when I go four wheelin'. Any takers? Good luck. - Tim
