Could be that when it rains or is wet out that water is leaking into your car under the hood under the vent by the windshield wipers on the passenger side and instead of being filtered out its going into the car on the passenger side floor. (check to see if this is wet after a heavy rainfall) and causing a short and rusting it out. this happened with my 2002 grand prix just this year. I got a water resistor for like $3.50 from a local pontiac dealership/parts store and put it in. Its easy to install and it poured out today and my car didnt leak at all.

My wipers and heater fuse blows as soon as I change it only 1998 ford escort


This would mean you have a short in either the wiring or the heater fan or wiper motor. If you have a multi-tester you can disconnect the negative battery terminal and use the OHMs function to test the wires going to the wiper motor or the heater blower. Only 1 wire in each plug connector should be grounded to the car body, not both. If the positive wire is connected to the car body it is a short.

Another way to check at the expense of a few fuses is to leave the power connected and disconnect the wiper motor connector, and insert a fuse in the holder and see if it breaks. If it does not break then it is in the wiper motor or wiring. By unplugging the wiper motor connector you have eliminated the path to the short.

You can do this test as easily by starting with the heater blower. Unplug the connector and then put in a fuse in the holder and if it does not break, the problem is either in the blower motor or the wiring to the blower motor. By unplugging the blower fan you have eliminated the path to the short.

Now you do not have to sacrifice a fuse each time if the multi-tester is set for 12volts instead of OHMs and you use the leads on the clips that hold the fuse. But multi-testers usually do not have alligator clips and you would need to
hold the test leads to the fuse holder.

On some models there is a blower motor resistor between the power source and the heater blower. Usually they do not short like you are experiencing. You could have a wiper switch malfunction in the steering column, which could also go away each time you disconnect the wiper motor.
Hope this helps

What is a fan switch


It either turns the fan ON or OFF. It may also allow the fan blade shaft to rotate at 1, 2, or 3 speeds depending on design.

BLOWER MOTOR RESISTOR


Local salvage yard would be an ideal place to get another one. After you change it, remove the blower motor and reach up into the cavity that feeds it air on the upper left.

You may want to wear a glove. The design on this generation Rodeo is horribly flawed. I pulled a squirrel-sized wad of rotten leaves and pine needles from mine after replacing the motor and resistor twice.

Like drinking a milkshake through a coffee stirrer, you know that's bad for a motor.

Heater quit


First of all check your fuses, more than likely just a fan blower fuse has gone bad.

The heater fan in my 2003 rodeo isn't blowing. I checked the two fuses 15A fuses under the hood and they look good. What else could it be? BTW this blower was replaced under warranty a few years ago.


The motor goes bad because leaves and such make their way down and clog it's air intake. Pick up a new one at your local auto parts store if you have to.

It's four screws on the motor housing, located under the glove box (2 screws) and the wiring is harnessed, so no sweat there.

While it's off, reach up into the cavity that feeds it air on the upper left.

Rear windshield wiper does not go back into the stored position. Motor seems to work ok.


I have same problem with a 2004 Tahoe. The wiper hangs up on plastic bracket and won't go back down into off position. Design flaw?

Change out the ac blower


unhook the battery find the blower motor unhook the power connection wire it will be a male female type connector most likely unhook it and remove the bolts securing the blower motor to the housing it should pull out with minor effort it will probably seem to have glue but it will be a gasket usually made of foam that sticks to it. If the foam is badly damaged find some simular foam at the hardware store reinstall reverse of removal.
