Wiper motor bad or what

[dickeymoore]

I have a 1980 Monte Carlo and early in the mornings the wipers dont want to seem to work unless i pull up on the wiper arm, is this a case of a wiper motor going out or what but they work fine in theevenings after work?Thanks

The way you describe it, it sounds more like a problem with the switch itself.

 

[dickeymoore]

ok Thanks

Now, your car is an '80. Would your wiper switch be on the dash, unless it was converted to a column mounted switch.
It sounds like your wiper motor is functional, but getting bad contact somewhere.

Check that your linkage is free. I had a truck that the linkage was binding slightly on. They moved slowly until they got moving after a bit.

These wipers are sensitive to being well grounded. Loosen and retighten the screws holding the motor unit to the firewall mounts. That might help.

ok

I'd try 469070. Really need the Chevrolet A-body 1976-1981 Parts & Illustration Manuals at your fingertips to easily track this stuff down. I gave mine away.
