Thanks for the wiring info. I did find a wire that was bent 90 degrees and poorly conducting, but there must be another wire or other issue causing my problem since I still have the issue.

Hi, the fuse panel under the rear seat has a fuse at #3 and a relay at #9. My mistake, not 6. Earlier vehicles had a circuit breaker. 2006 and later had a relay.

Txs for your response. I have a 2006 Buick Rainier with 4.2L. I have replaced the relay and it made no difference. Initially pulling the relay would make the wiper work again. Now I have to pull both to make it work. I can try pulling just the fuse, but will need to wait until it fails again...

Can you show me what the switch looks like and where it is located? Txs

I have been pulling fuse 3 and relay 6. They are under the rear seat.

I pulled the rear hatch cover off and checked them at the motor.

This is brilliant advice, used it myself. Replace two of the 8 mm long fan bolts with 30 mm long bolts. Remove the other two bolts, now you have all the clearance you need to remove the fan and replace the water pump. It saves a ton of time and effort.

Hi to all, having a problem with the rear wiper. It works for a few weeks to a month and then stops working. Pull fuses, reinstall fuses, works for another 3 to 4 weeks and then stops working. Motor is new, replaced twice. Ground and power is good. No rust on my vehicle, so it's not a rust...

Hi guys, just ordered my third Dorman exhaust manifold 674-990 and it looks much better than my previous two did which were made in China. This one is made in India (dated Sep 2024) and comes with a beefy heat shield. The old Dorman exhaust manifold shields looked like crumpled up tinfoil and...

Thanks Mooseman. The grease was pretty dried out inside the disconnect. I think the right move was to replace both. I recently had to do the seal on the driver side. Hopefully I am good for at least another 10 years!

AWD is working again!! Hi to all, I know it's been a while, but I finally got a new intermediate drive shaft and the correct AWD disconnect for the Buick Rainier. It uses part number 600-116 (not 600-115). This part is for vehicles that do not have any controls on the dash for AWD. Bought the...

Thought you guys and gals might be interested in a car nut who massaged 1000 hp from a 4.2L engine...

Strangely when I spin the front driveshaft it's quiet. I tested the AWD with all four wheels in the air and that's when I could hear a scraping sound coming from the front right corner. It doesn't seem to make any noises while driving on the road.

Hi guys, with all four wheels on the ground I tried to turn the front drive shaft by hand and it spins no problem. Does that indicate a stripped intermediate shaft? I believe it does from the posts I have read.

Thanks Tollkeeper, I appreciate the advice. I need to decide whether to take it apart and inspect, then order parts or order parts and then take apart. I would prefer not to disassemble and reassemble too many times. It will take at least 7 days to get the ebay intermediate shaft. That's a long...
