Is there a fuse for power windows?

According with the Ford Owners Manual (page 226 and next) I suggest to check the next locations:
- Battery Junction Box fuse # 6-60AMP will feed Central Junction Box ( under driver side)
- the inline circuit breaker #47-30AMP, through the Accessory Delay Relay, powered by fuse #17-15AMP to the Window Control Circuit.

Check the fuses, and for 12v at the points. Then check for 12v at the driver side door switch pannel.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

My blower stopped working I replaced the resistor and it still doesn't work! And I don't wanna have to buy a blower if its not the problem

Hi Stickboy.
What you could do to determine if the problem is a defective blover is to supply the blower with 12V directly. There must be a connector somewhere where you can disconnect the blower from the electrical system. In the connector you will normally see 2 wires - red & black. Connect 12V to the red wire and ground to the black wire. If the blower is working by this direct supply the failure must be looked for somewhere else.

Assuming the blower is OK - the next step is to measure if 12V is coming to the Blower resistor. If no a various reasons could be the problem.
I assume that you have checked the fuses already. If no - it is a good idea to check.

The heater fan just stopped...

Check fuse #14(10amp) located in fuse box under driver steering wheel behind the lower dash cover.
Check fuse#12(40amp) located in fuse box under hood.
Replace fuse(s) if any are blow.

If fuse are good.Check blower and transisto next.
Do steps 1-3 with turn key on
1. Unplug connector and check for 12v at the blue/white wire at the blower motor(2-NAT)
-if there's no voltage you might have a bad relay or open in the wire
-if there's about 12v, go to step 2
2.Plug connector for blower motor and unplug connector for blower transistor(4-NAT). Take a jumper wire and jump the blue/black wire to body ground.
-if blower does not run, replace blower motor
-if blower motor runs, go to step 3
3.check the black wire at(4-NAT) for good ground.
-if you have good ground, then replace blower motor transistor.
good luck

Park/Tail lights not working. Brake/signals are

Before going ahead and spending money on a new module, test it first. The module is located under the steering column. You'll find a Brown wire on one of the connectors (i just looked at a wire diagram). Do no disconnect anything. Back probe the brown wire, which is the power feed to your park lights. With the lights off, there should be 0 volts on you voltmeter. Turn the park lamps on, There should be 12V. If there is not 12V, disconnect the connector and try to check voltage at the pin that feeds to the brown wire, if still not 12V, replace the module. If you do get 12V, then module is ok, find where the 12v is being dropped before making it to the lamps.

12v accessory plug in

the first step is to check the fuse it should be labeled as CIG or AUX
if fuse is not open (blown) check for corrosion and power at ether end of the terminal (where the fuse goes in) using a 12V test light. If it does not light then the problem is between the fuse panel and battery, but if it lights check the power side of plug in (the sides are the ground and the circle in the bottom is the positive) with the test light. If there is no light that means a disconnected or cut wire on the positive side, but if it does light then there is a cut or disconnected wire on the negative side ether one may need to be further investigated and repaired.
also remove panel and check to see if the wires have been unplugged from the end of the plug in
