I think your problem is the power transistor. Did you change the power transistor with the blower motor? I think i mentioned this before, if the power transistor is blown then the blower motor will not get any current in any position (other than high) b/c the power transistor will have an infinate resistance (cause its open) and will use all the voltage, leaving nothing for the blower motor. In the high position, the current does not go through the power transistor.

 

is the power transitor the same thing as a resistor, or atleast what someone would call a resistor? i talked to a mechanic and he was sure it was the resistor. except i did a search for a resistor and found nothing.

the leak is gone. got a new windshield. there was a big seal problem there. replaced the blower motor and relay. i want to try one more thing before i bring it to the shop.

can someone send me a schematic of where the transitor is (or how to get to it)? and possible a good place to find one.

 

hi lo oreilly list a blower motor resistor for my car - 88 honda civic.
cost is 23.99
