Window Switch

[Jaime Tucjer]

When using the switch on the drivers door it blows the fuse. Could it be a bad switch?

Yes it "could" be a bad switch.

It "could" also be:

• Bad motor
• wiring fault
• tripped circuit breaker. CB should reset after cool down.

Some testing with a Volt-Ohm meter (VOM) could narrow this down.

A resistance check of the motor windings would be a good first test. Or run the motor directly from battery to confirm that the motor works.

At the very least consider performing a visual inspection before replacing the switch as it's an expensive part to replace on a guess.

OBTW; it might be handy to mention the model year of your Mustang. Why? Because many model year mustangs the windows are protected by auto resetting circuit breakers.

I was taking the switch out to test then it started working. So i'm thinking a wiring issue

Easy to check the switch with your VOM while you are in there too.

I will definitely will
