I had wiper problem in my 94, just clicks from behind the dash as you describe.
Replaced the switch and the motor, no dice.
It ended up being a square plastic module under the dash.
Luckily I had a spare parts truck, swapped them out and no problems sinc.
I am new here but I signed up to be a supporting member since I figure it’s worth it for any good info. Plus to get rid of the ads.
Well I am getting ads and cannot log into the supporting members forum.
Is there a waiting period for noobs on the site?
