it wont move...my passenger side mirror will still work it just suddenly happend one day..any ideas

Hmmmmm, well I never had Electric Mirrors in a GM car but my other cars have a switch that controlled the left and right electric mirrors. Is there a R/L position switch in these H-bodies? If so is the switch positioned for the Left/Drivers Mirror?? :?: : This answer oughta "shock" some of the electricians here to punch in.

Not sure how this slipped by...

And Ol'Timer..I think you are on the right track to diag this..

ya I move it to the left and the left side moves...move it to the right nothing happens...no noise no anything

-any help appreciated

There'* most likely a break somewhere in the connection between the mirror and the switch. You'll need to test the circuit. I guess it could be the mirror motor but I would bet againt it. I defer to the Boost Man on this one.

I'd start by checking the switch. There may be a break either in the switch or the connection going to the wiring for the driver'* side.
