I took out my ac about a month or 2 ago and after that my blower motor still would blow in air and the heater/defrost still worked but now it's not working and i checked the fuse and relay so my question is what else should i check before i take it in to a shop? and the lights for the ac/defrost button don't light up anymore. any help would be appreciated

 

use a volt-meter and test at the blower motor connection. If you get power then you probably need a new blower motor, if no power (and all fuses are good) check out the climate control

 

where are the positive and negative on the blower motor located?
