I have three problems- I bought this car used. I was told that the blower motor for the ac/heater may be out. It definitely is. I discovered that it could either be a resistor or the blower motor itself. At least that is what the guy at Auto Zone told me trying to sell me a blower motor. Other issue is that the windshield wiper reservoir is full but when I push the button for the fluid to release, it does not make a noise and nothing comes out. I assume it is a motor of some sort as well. Third problem is that when I went to replace the fuse for the radio, i discovered when I turn the car off the radio stays on even when I actually turn the sound off. Sounds like a short. The last problem I really am not worried too much about. but as winter is coming, I would however, like to find a solution for the first two problems. jrclark

Check the fuse or the circuit breaker.?Remove wires at the blower motor.One will be the ground wire,black,in color?? the other will be the hot.If there is only one then the motor is grounded by its mounting. Check wiring diagram.for colors or use an inline fuse 20 amps. in the power test lead Run a ground wire to the other. A premade set of test leads are very helpful.This will test the motor.The fuse may blow if the leads are reversed or the motor is shorted,or draws too much current.If motor tests ok,repair the open.Test the switch and the high speed relay,then the resistor packl All with finction of the blower switch.No slow speeds,bad resistor pack or switch,check resistor(visually),no high speed with switch?Bad highspeed relay. A wiring diagram will be of help,in checking points in the circuit where the color code is used.Without a diagram is a guessing game and takes more time.
