Jan 20, 2003 (1:11 pm)
Mine did it as many other owners had the same problem. I got the fix for it on a post on Delphi and did it, and it fixed the problem. Here once again is the service bulletin and instructions on how to fix.
Rear Wiper Jumps When Fog Lamps Turned On (Connect Auxiliary Ground to Rear Washer Pump)
2000-2002 Chevrolet and GMC C/K Utility Models (Suburban, Tahoe, Yukon, Yukon XL), 2002 Cadillac Escalade
Condition: Some customers may comment that the rear wiper jumps when the fog lamps are turned on.
Cause: Electrical feedback from the fog lamp circuit into the ground of the rear window washer pump may cause this condition.
Correction: To perform this correction, you will need to obtain the following items:
1 - A J 38125-B Terminal Repair Kit. Obtain the following parts from the kit.
2 - P/N 12077411 (Terminal) from tray #2
3 - P/N 12089496 (Ring Terminal) from tray #5
4 - A 508 mm (20 in) length of Black, 0.5 mm (20 gauge) or 0.8 mm (18 gauge) wire
Isolate the rear washer pump ground circuit by performing the following steps.
1 - Remove the left side fender to radiator tie bar diagonal brace.
2 - Remove the battery.
3 - Remove the battery tray.
4 - Remove the bolt that secures the washer bottle to the upper radiator tie bar.
5 - Raise the vehicle on a hoist.
6 - Remove the lower washer bottle mounting bolt.
7 - Locate the rear washer pump motor, mounted into the washer solvent bottle under the hood, and disconnect the wiring connector for the rear washer pump (Dark Green/White stripe and Black wires).
8 - Remove the black wire from the connector. Cut the wire and tape the end to seal out moisture intrusion. A non-sealed wire will allow moisture to wick up the strands of the wire and may corrode other components/connections.
9 - Slide one end of the new wire through the weather pack seal which was removed from the old wire.
10 - Properly attach the 12077411 terminal (crimp and solder) to one end of the new black wire.
11 - Properly attach a 12089496 ring terminal (crimp and solder) to the other end of the new black wire.
12 - Place the new terminal and wire assembly into the rear washer pump connector and properly position the weather pack seal.
13 - Reconnect the connector to the rear washer pump.
14 - Route the new black wire down to the attaching point on the frame, same location as the battery ground. Follow the battery cable routing.
15 - Remove the ground to frame attaching bolt.
16 - Clean the battery cable and G100 ring terminals of contamination.
17 - Install the new wire ring terminal between the battery ground wire (5) and the existing G100 ground wire (3). Tighten the engine wiring harness ground/negative cable bolt to 25 N·m (18 lb ft).
18 - Install the lower washer bottle retaining bolt. Tighten the bolt to 9 N·m (80 lb in).
19 - Lower the vehicle.
20 - Install the upper washer bottle retaining bolt. Tighten the bolt to 9 N·m (80 lb in).
21 - Install the battery tray. Tighten the battery tray bolts to 9 N·m (80 lb in).
22 - Install the battery. Tighten the battery hold-down retainer bolt to 25 N·m (18 lb ft).
23 - Connect the battery cables. Tighten the battery cable bolts to 17 N·m (13 lb ft).
24 - Install the left side fender to radiator tie bar diagonal brace. Tighten the front end diagonal brace bolts to 9 N·m (80 lb in).
25 - Reset the clock.
26 - Advise the customer that all memory modules will have to be reset such as seat, radio presets, and the like. Also advise the customer that the transmission shift points may feel somewhat different. This will change over a short period of time as the transmission adapts to the customer driving habits.

#3343 of 6471 Oxygen Sensors
Jan 21, 2003 (7:58 am)
I have a '96 Tahoe 5.7 4x4 w/ about 110K miles on it. I bought it new and pretty much keep it up. Few months ago check engine light came on a dealer replaced on of of the O2 sensors.
A local mechanic told me that replacing all 4 O2 sensors will dramatically increase fuel efficiency? Just wondering how often should the sensors be replaced? They are not cheap. The dealer wants $115 per sensor + installation.
Also, any recommendation on the type of plugs I should be using. About 15 months ago, I had the dealer install Bosch Platinums and paid a premium for them (price+installation). Should I go back to Delco Platinums or NGK is a better choice?
Thanks in advance on your feedback.

Had the same problem. After installing the $20 foglight override switch problem resolved and took only 10 minutes to install.
#3345 of 6471 Using 4WD on the Hywy

In reply to post # 3284
Davids1 - You asked if I did much hyway driving in 4WD. Most of my 74,000 miles on the 01 is city, but about 1/3 is hyway. I didn't realize that it would be a problem.
I need to get to the bottom of my problem then with the amount of play in the wheel expecially on hwy driving. I did get new tires the new Goodyears for SUV's. BUT it still isn't very tight.
Any insite would be apprectiated.

Dave5319 - I only use a very mild detergent on the dashboard, and at times only a damp cloth.
My Yukon is not under warranty so I'm not sure if there is anything that I can do?
#3347 of 6471 Accident in 01 Yukon
Jan 21, 2003 (3:36 pm)
My daughter was hit on the front passenger side of our Yukon by a guy going 45-50 mph. The Yukon spun around, but didn't flip. The cabin was not disconfigured & it really took the brunt of the accident well. Knowing what happened, I was really surprised that there wasn't more damage to the vehicle (but happy there was not)
I really was thankful that everyone in the Yukon was basically OK.

Sorry to hear about the accident! Hope your daughter and everyone gets back 100% quickly.
