Having problems with your 1990 GMC Sierra ?

We got a lot of snow and I was trying to clear my windshield. Turned on the wipers and one wiper stopped. The other still works. I have a feeling I know what is wrong, but I just need to know if I can get to the wiper arms underneath the cowl or do I have to go behind the dash.

Answers :

You can get to them from under thev cowl. Just look at the cowl and you will see the screws that hold it in place. Just remove them and lift the cowl and the linkage you want to get to will be exposed.
No from the cowel is were you get to it, but if theres a nut holding the arm to the shaft check that first,hope this helps.
