UGH! What is up with this truck! (wipers)

[PaHumBug]

I've replaced 3 wiper modules on the 4 H2's I've had. Getting the cowl on and off is the biggest pain, but I'm getting pretty good at it.

PHB,
Are you doing the "sealing" that some have instructed on here after you install the modules?

[HUMTECH]

Had a hummer in the shop today with exact problem, wipers kinda vibrated on the wind shield and wouldn't move. Helped them a little and they made one swipe then got stuck and vibrated again. Found the wiper transmission pivot points were binding up and not allowing them to move freely on their own without help getting them off the position they were stuck on. had to order a wiper transmission assembly which comes with new motor. should have it Friday afternoon ill post my results.

Thanks Humtech,

Yes, used black RTV. Never had a problem again. Sounds like this might not be your problem though. But if you're in there anyway, I would recommend sealing the module before it leaks and dies anyway.

PHB,
Yeah I would definitely, but it sounds like from HumTech that it probably going to need replacing.
UGH I hate it when you have the money set to buy something for your truck, and then something breaks and makes you spend that money elsewhere

HT,
Not sure if this matters or not, but the other day I had noticed my wipers were on.
I noticed that even though there werent moving, I could hear the motor buzzing at the times when the timer would allow them to move.
I was sitting in a parking lot and I hear buzz.......... buzz........... buzz...........
Then I realize it was the wipers and turn it off and the buzz disappeared.

Was this similar to the situation of the truck that came in?
Just seems that the motor is still good (since it is still buzzing) but that the gear or track that causes them to move is off. Maybe I am wrong.... and so i ask you

[HUMTECH]

Exact same issue sounds like. Just replaced the assembly on the one at work before lunch and problem solved

[jsbihn]

so there is no way to repair the part that is causing the issue without replacing the whole unit?
Just cant see spending 200 bux for a new motor if this one works proper but say the piece that connect the arm to the motor is stripped and I could fix the piece for cheaper then 200 bux

(ie. i have repaired the shift linkage issue on my truck with a 25 cent nylon nut that i got at an auto parts store versus having to buy a whole new linkage assembly for 125 bucks since the only way to get the oem nylon piece that holds the linkage assembly was to buy the assembly.... and when that fails (if it does) I will replace it with the 12 dollar piece that i made that will NEVER break)

I know it sounds cheap... but I have to watch my wallet in this damn economy. Plus again, I love knowing I fixed something (especally for less) and that there is a little more "Me" in the truck and a little less "OEM"
