#3756 of 6469 rear wiper problem unrelated to fog light
Jun 07, 2003 (1:52 am)
It's still a ground issue, follow the the enclosed instuctions and it will all go away.
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.

I don't know if anyone has discussed this already, but I am wondering about the GM coupons that people have been talking about. What kind of discount will that give you? Any help would be appreciated.
Jun 09, 2003 (10:35 am)
I have an 02 Yukon SLT, and I was wondering if any one knew if the front grille is interchangeable with the grille on the denali? If so could you please steer me in the right direction of possibly locating one. Also has anyone with a sunroof had an overhead entertainment system installed AM. If so how is it working and what type did you buy. I appreciate any info I can get on this.
#3759 of 6469 Tire size for Tahoe
Jun 09, 2003 (3:34 pm)
I recently purchased a 2000 Tahoe and am replacing the Firestone LE tires with Michelin Cross Terrains. OEM calls for 245/75/16's but the vehicle has 265/70/16's on it now. I know the 265/70/16's look beefier and that I'll get a softer ride with with the 245/75/16's, but what are the pros/cons between the two. I am specifically concerned about gas mileage differential. My driving is mostly highway travel and carting the kids around town.

but have you looked really close at a Denali Grille. Plastic, and I think cheap looking at that. I had the same thought when I had my Sierra until I looked closer. BUT, the answer is yes. I don't know for sure, but I suspect to change out just the "mesh" part probably requires cutting. There's an ad in the current Sport Truck magazine for both the Denali insert (actually it's an overlay) in Stainless Steel for $165, and the complete Sierra Grille with the O/E Denali insert in it for $645. (Maybe the Stainless Steel looks better than the O/E plastic). The same ad also has several Custom Billet grilles. Hard to decipher, but I think it says JBM Sport Truck Accessories. It's on page 11. If you pick up any Sport Truck or Truckin' magazine there's always tons of ads for more truck stuff thatn you'd ever want or need. These are about the only magazines I don't mind being filled with Ads!
#3761 of 6469 Z71 wheels and tires on a 4X4 LT
Jun 13, 2003 (6:10 am)
I have a 4X4 LT and want to put on a set of wheels and tires off a Z71. Has anyone done this and experienced any problems. I don't forsee any but thought I would check. Thanks,
#3762 of 6469 Z71 tires and wheel
Jun 16, 2003 (11:06 am)
This issue was discussed very early in this thread.
The Z71 has 17" wheels and the LT and LS have 16" wheels. While I believe the bolt pattern will fit, you will have problems with things like the speedometer and other electronic systems, etc. (all of which are calibrated to a 16" wheel.) Also, my understanding is that the suspension is very specifically tuned for a 16" wheel. I test-drove a Yukon last year with aftermarket wheels and tires on it. It also had the autoride suspension. The suspension seemed to be very messed up and it didn't drive well at all.
That's my $.02.
(I ended up just replacing my LT Tahoe wheels with the 16" wheels off of a new 03 Silverado. It looks great and it didn't mess anything up!!)
Jun 16, 2003 (3:02 pm)
The 16" wheels could have the same overall diameter as the 17". It depends on the aspect ratio of the tire.
#3764 of 6469 16" vs 17" Rim
Jun 16, 2003 (5:19 pm)
Just what is/are the advantage(s) of a one inch difference in rim diameter?? I don't see how a 1/2 inch in height makes much difference in handling unless you're on a race track. Seems to me the overall diameter/width of the tire is what counts. A 2 or 3 inch difference might be significant.
Jun 16, 2003 (7:22 pm)
I hope 4burb doesn't want to do this to improve his handling or comfort. With the 17" wheel and off road type tread on the tires, he is significantly degrading his handling and adding noise and harshness to his ride.
Are these sneakers really that cool?
