2009 Ford Mustang GT/CS; Wiper's inop. Motor and switch are brand new. Circuit 2026 (constant 12v+) is good, circuit 2025 (ign 12v+) has no power. Fuses for both circuits are good, and I have 12v+ positive...

Could it go through a body control module some where? In most cases Key,to switch,then to motor. All the speed and park should be built in the motor/gear box.

1993 mustang conv all power winows and door locks quit working ?

Sounds like your ground part of the circuit is not working. Check in the door opening for broken wires-that's where they get stretched and break. Identify your ground for the windows that comes from the switch and goes into the cabin to a ground location-like behind the kick panel under the dash, maybe located there. You can use your multi-meter to check continuity of ground wire and also if the ground is good. Like this: your red lead to a wire or terminal that has power on it. Then connect your black lead to the ground wire terminal at the switch. If the meter shows voltage, then you know the ground is good. If the ground is not good, the meter won't register. See?

Blower motor not working. fuses appear to be ok. was working fine yesterday. any ideas?

Test the blower motor, turn on the switch and then with a test light conect it something that is grounded. Check for power at the harness, then connect the test light to the power side of the battery and test for grown at the harness if you have power and and ground replace the blower.

Wiring problem on 65 mustang

If your car is a automatic, you may need to check the Neutral safety switch on the transmission. These are know for going bad. There are two connections on the firewall that are on short plastic two wire connections. One is a reverse light connection and the other is a neutral switch connection. If this is the problem shorting this plug should allow the car to start. You have to find the right plug first. I think it is red or similiar and has one male connection and one female connection in the same rubber plug two wire housing. Attachewd is a pic of teh plug to look for on the upper firewall.cobra65k.jpg

Fan motor works on high

Really common problem on Fords. My '00 vic had it and my friends 06 mustang had it. The problem is the blower motor gets old and starts drawing too much amperage. The motor is controlled by (on manual HVAC systems) by a nichrome resistor bank located near the heater core. The extra amperage blows the thermo-resistor in the bank, and also does some damage to the corresponding harness. The reason it work's on "HIGH" is because that setting bypasses the bank completely. You can fix the problem pretty easily yourself but it is sort of annoying. First go get a new blower motor, either from Ford or some other place like Napa or autozone. Probably one of the latter because sometimes it seems dealer's aren't always the most cost effective solutions =] Now head on down to Ford and pick up the resistor bank (and most likely the harness, but check if it's burnt first) park your car, let it cool down, and pull off the radiator cap, keeping it on the hole (this keeps the pressure equal, and just set it on the hole so no random stuff gets in) pull off the coolant lines to the heator core, unbolt the resistor bank, set it next to the next new one, and wire up the new harness one wire at a time. plug in the new one, bolt it in, and reinstall the coolant lines. then put in the new blower motor, it should be on the lower passanger side on the engine bay. Now go enjoy your new fan speeds!
