Q: Where is the location of the blower motor relay?

asked by on

My heat/air will turn on sometimes. Other times it wont. It wont blow either hot or cold. It either works perfectly or doesn't work at all. We are thinking its the fan or the motor.

My car has 156000 miles.
My car has an automatic transmission.

Depending on what model Kia you have the blower relay is in the instrument panel main fuse relay box. The blower intermittently may not come on and blower is bad and binds. Tap on blower to see if it starts. If it does then replace blower.
