On my 2000 disco, I have a funny sound under the dash on the passenger’s side, I hear a continuous tick whenever I turn the power on the heating control. It sounds like the fan that blows the heat is going bad or rubbing when it turns. Any thoughts? What needs to be done? Cost?

 

Sure, you probably have some debrit stuck in the blower motor behind the glove box.

What is the best way to access this to clear anything in there?

 

I believe if you open and empty out your glove box that you can then drop the glove box down and out of the awy to see the blower motor.
