The blower motor in my 2002 Si Hatchback (EP3) started working intermittently a few months ago with no noticeable pattern. That was when I was still using the AC. Now that I need the heater and defroster, I was getting tired of it not being dependable because I did not want to go through winter without heat and the defroster part of the time, so I had the blower motor replaced. It worked for a week or two without any problems, but now it's off again. My guess is the blower motor was not the real problem and now I am out the price of the that repair. So what else could it be? I haven't been able to figure out if there is a relay that could be bad, or something else in the circuit.
