when i turn my heater fan on all igets is a tick from under dash fan not blowing help ?????

 

I just finished fixing the same problem with the same symptoms on my Corvette, in my case it was the HVAC relay. I'd start by checking fuses just in case then check the relay. Could also be the blower motor itself, check to see if you are getting power to the relay/blower motor.

 

lots of info here about resistors,etc,havnt heard yet of a bad motor
