    The Audi in question had the thermostat missing, at the begining of the winter the customer wanted heat so we put a thermostat in it, we thought that the thermostat was in and just froze open and when we took it apart it didn't have a thermostat at all.  That leads me to believe that there was a fan problem before he bought it and they took the thermostat out to stop it from over heating.  Now I am trying to fix the fans and I was about to pull  them out when I went to unscrew the possitive wires from the buss they were in bad shape.  I have never seen what I believe to be a possitve buss to supply power the fans.  That said I am wondering how to jump the temprature sensor so I can check if the power is getting to the buss and just not to the fans due to a conection problem or if the fans need to be rebuilt still?  Thanks, Josh

What r the colors of the hot and ground wire's on radiator fan for a 2005 doge ram 1500 I'm wanting to hard wire the fan until I can get to the shop get it fixed I need a quick fix

I checked the wiring diagrams and did not see an electric fan.
The hot for the ac condenser fan is light blue/white and ground is black/orange.
You could use a meter and check the wires for ground and hot also.

I have a 1987 chevy s-10 blazer v6 2.8 fuel injected dat starts up but dies out?

sounds like the fuel pump is not staying on or the ingtion switch doesn't make in the run position ( happens alot to vehicals take have lots of keys hang on the switch) The sparp going away is easy to check with a test light theres a connector on the distrubutor that has a heavy red wire plugged in that goes to the B+ terminal it should be hot with the key in the run position. if it's dead fix the connection at the ingtion switch ( it's on top of the steering collum and all but one wire will be hot with the key on, that one comes hot in start) if it's good the fuel pump is next it has a fuse on the passenger side firewall next to the fuel pump relay. Fuse bad or relay bad or dirty it'll act this way. The start wire entergizes the pump in crank position. then the oil pressure switch takes over and keeps the pump on. theres 3 wires on the oil pressure switch the center wire works the light the left one is fuel pump fuse power and the right one is the fuel pump. the oil switch can go bad and the connection can go bad the wire can fall off or get broken. the wire to the fuel pump may not get all the way to the pump.. You can add power to any wire on the swich with out hurting anything. all of the wires will be hot with it plugged in and running. unplugged two wires are hot with the key on ones the light ( oil Pressure light) the other is the key on power for the pump with oil pressure the switch closes and the pump comes on and it'll be powered right off the starter as it's cranking. If the switch is leaking oil its likly failed too.

Air suspension not working

There are sensors for each corner. It sounds more like a sensor than a bag because your pump would keep running trying to raise the low corner. Your pump is shuts off.

Now you did not say if the pump will lift the other 3 corners without you having to hot wire the pump. You probably know about the shutoff in your trunk.

You should be able to find used parts in a Salvage yard. You can try Autozone or Oreillys for aftermarket parts. But the dealer and some places can use a diagnostic plug to quickly ID the problem.

Also, Ford and Mercury have Air suspension on Crown Vics and Marquis. The parts would be cheaper than those with a Lincoln badge. We used Crown Vic parts on a Mark 7.

The ignition KEY to my 91 camaro broke i want to hot wire it for now what would be the least destructive way and how

Unfortunately your key has a chip in it which prevents anyone from hot-wiring it. Did the key break off inside the ignition cylinder on the column? If so, you should be able to turn the car on right?. If you have to replace the ignition cylinder you must have the key in the cylinder to remove the old one. I wish I could see this up close so that I could fix it for you. Keep me posted please.

Dash lights and tail lights out. Fuse is good. Circuit relay makes noise when light switch is turned on to parking lights. Do I have a short or bad switch? Everything else is working. This is a 95 Ford...

You are not gonna believe this fix. Same year car, same problems. EXCEPT the final straw for me was when the dash guages started to smoke me out of the car. Pull the instrument cluster and identify the location of the ground circuit. Its all the flat ribbon style solder-wiring stuff. Also look for any obvious hot spots or discoloration. For me, the ground wire to this cluster was getting extremely hot because of the load the previous owner had put on the circuit. Had the car stereo fed from there. dont do it. Anyway, as the circuit gets used, the ground gets hot because it is no longer the right size required for the intended load. (remember the added car stereo load) Mine finally melted, so the fix was to replace the section of bad wiring with a jumper wire the same size or slightly larger and solder it into place. I would start here and at least rule out that possibility first. Good luck!

2004 Expedition Wiring Color Codes

brown would be the parking light hot wire
green / white would be the blinker hot wire
black yes ground ,
but according to the schematics , **** this color combination only applies to the left front

the right front should be :
brown would be the parking light hot wire
black ground , and a white / light blue would be the blinker hot wire

do you need the rear colors ?

brown is parking on both left and right rears
black is ground on both
light green / orange left blinker / stop light hot wire
orange / light blue right blinker / stop light hot wire

Blower control switch

jumper it across from the blower motor to the pos battery cable to see that your blower motor is still working.the best way to do it is connect a wire to the pos battery long enough to reach the blower motor to see if it works. if it is the switch youll have to change out the panel where the sswitch is located and if i remember right its all one unit anyway.i can tell you how to jumper it where it will run when the truck is running and shut off when you shut the truck off to get you through the winter if you need me to

93 pontiac grand am

This happened to me on my 93 grand am. I also like you got new sensors and a new computer which did not fix the problem. It turned out to be a cracked wire at the battery. Thats right a wire on the positive side of the battery that wasn't even broke all the way through. I re spliced the wire and VAROOOOM it fired right up.
