Another day another problem.

Wut up firebird homeys.My drivers side power mirror does not work.However,when turn the switch to operate the passanger side mirror it all works except for the down botton on the cursor.any body have the same problem or have experience fixing those. I could really use some help .thank you.

Basicly,I dont know if its a bad switch or mirror motor(if there is 1)I am leaning towards the motor being the problem because the switch works for the passanger side.Is there any truth 2 that?
