Only one windshield wiper seems to be working on my 2004 Pontiac Montana?

Question

After yesterday's great weather (not really) only one windshield wiper is working on my 2004 Pontiac Montana. And if I turn them on, the one that is working catches the one that is not and tangles.
There was ice buildup where the wipers are supposed to go all the way down near the hood but I thought I got it all out.

Answer 1

i own a repair shop,and it being an 04 model it may be covered by warranty on this one id call them to make sure ,you might get this one repaired free of charge on it,what happened to it is one of the arms has come off for the linkage ,good luck with it i hope this help,s.

Answer 2

You probably have moisture on the circuit board that is bolted to the wiper motor. You can take it off and clean it with electrical contact cleaner and reseal it with a little RTV when you put the cover back on. That is the same problem I had with mine. I found a new motor and board at NAPA for $80.00 but tried cleaning mine first and it has been fine for 4 months now. If you do try to clean it make sure you mark where the wiper cam and wiper motor shaft so you line them back up right when you put them back together.

Answer 3

sounds like you popped 1 of the arms off.the best way to do that(once you get it fixed)is when its cold outside,park your wipers about half way up on the windshield.that way you can clean them better,when theres ice on them.just turn the wipers on and when they get about half way up on the windshiel,shut off the engine and they will stay there.
