I have a 94 blazer fullsize with power mirrors. I am having issues with the drivers side mirror will not come in and the passengers mirror will not go out. I bought a new switch thinking that was the issue and that switch does the same. I used a test light to figure out what wires control each direction and then i heard a pop noise under dash and now have no power to my switch. Is there a fuse or circuit breaker i need to check or how to i fix my issue.

Thanks
Jason

 

im having same problem too bro.ive got a 99 blazer and they used to work when i got it 11yrs.ago but then in time they slowly started to not work.so last yr. i decided to buy another switch from ebay put it on and still not working sometimes if i really pay attention to the mirrors very carefully it well slowly move and sometimes it wont.i was gonna do the same thing u did by testing connections.

 

On a '93 the stop/hazard fuse is connected to the mirrors. There is a 'mirror control assembly' mounted on the right side of the instrument cluster. Not sure on a '94 tho...hope this helps......
