Hello forum guru's, My 02 XL's wipers stopped working yesterday during a snow storm. I don't think it's something like a fuse or relay or switch,(hope it is$) but last week I had to reset the clock due to a power surge or something in the vehicle.

Anyone out there had similar experience? Maybe other issues in store for me? Any help, ideas would be appreciated.

Thanks

My 96 S10 had a recall for the same thing. They quit working on me in a blinding rain storm at night on the interstate with concrete barriers on both sides of my lane. Not making it up. Scary.

I don't know what the 2002 has, but my 98 Yukon has a circuit board under the cover on the wiper motor that had problems.

I have an 03 and had to replace the circuit board in it. No problems once I done this.

Thanks all for the suggestions and help. I'm going to open up the circuit board on Monday and see what it looks like, maybe do some spot soldering. I'll post the results that evening. Once again, thanks.

Free tip---works all the time!!

 

These wiper motor circuit boards lose their ground. SO, all you have to do is fabricate up a ground wire. Connect the ground wire to the wiper case itself, next to the circuit board. Now connect the other side of the wire to a good sheetmetal ground, such as the firewall.

 

When I do this, I use 2 small self-tapping sheetmetal screws. For the ground wire ends, I used small ringlets; or "eyelets"

 

Save yourself the headache. Add the ground wire. Your wipers will never mess up again !!

 

Here's what you want:

I usually drill thru a mounting "ear" on the motor case, and then thru the firewall.

Take off the wiper arm and see if the motor turns like it should. I had a simular problem, all I had to do was replace the wiper arm...worth a shot I guess!

Sorry for the lagging response, and thanks for all of the suggestions. I'm happy to report that the issue was resolved. I removed the cover on the wiper motor exposing the chip board, there was a blown resistor on the board that was causing the malfunction. I found the part locally for $72, more than a ground wire but the wipers are good as new. The whole process lasted about an hour to fix.

Thanks again everyone and good luck!

      Cold start Miss, oil in cylinder

      By asilverblazer · Posted

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
