Hi everyone....I have a prob here.....i bought a '94 escort from the lady down the street and the blower doesnt work....not on any setting....when i hit the button in the middle to turn on the AC the compressor cuts on and u can feel the car idle down so i know its working but no blower....i thought it was the motor since the car sat for a while b4 i got it but it wasnt....then i tried replacing the blower motor resistor but that didnt fix it....so i got a new control panel with the cables and everything and that didnt fix it....now i just got back from the ford place and they said i had a bad connector going to my blower motor resistor so i changed that and it still dont work....now im stuck and wondering whats going on....also my cooling fan by the radiator doesnt work either......these connected?....i have the chilton manual and everything but it doesnt say how to diagnose just how to replace....well i'vealready replaced what i know of.....any help would be GREATLY appreciated.....thx in advance

The first thing to check is, is the blower getting power, does it have a good ground. Use a wiring diagram to trace the electrical circuit. Are you sure the blower motor itself is good?

I'll bet you a beer that your problem is the single connector under the passengers dash which plugs into the blower motor. It gets corroded a bit, then eventually stops making contact. Some are melted and such as well.

Pull the connector off, and clean it up the best you can, as well as the tab it goes onto. Then try again. ;)

thx for the replys guys but yes i have already made sure that the blower is getting power......and i have already replaced the plug u were talking abuot right up under the blower area.......today i took apart my fan switch and saw a little discoloration on the points so i cleaned the points up good and put the switch back together but same thing.....not blowing.....i think it has to be a ground problem or a relay i dont know about causing this because everything i find out about i replace and it still doesnt fix it.....im about to goes nuts lol.......it about to start getting hot and i really would love my blower to be working right ya know

UPDATE:

ok i just came from outside where i looked at a wiring diagram and i have 12vdc at all 5 wires going TO the blower motor resistor when the control is in the OFF position but when i turn the unit on 1-4 of the blower settings i loose power to the 4wire side of the resistor...how come?....seems like it would go thru when it on and just sit there until called for.......does this mean i got a bad switch?.....it has already been replaced before in the new control unit i got but it was used....would that switch be bad tooo ya think?...

Well its possible that yes the switch is bad as well.. but it sounds like a loose ground if ur just losing power. a new blower and a new resister given that the switch is operational it have a very high possibility that you have a weak ground wire. or broken inside the insolation.

Does the motor itself work? Pull it right out, and put 12v on it from your battery, using a couple fairly thick wires. Need to rule out the motor itself as well.

yes the motor does work....i totally removed it and used jumpers and the motor turned right on.....ALSO if i jump the springs on the resistor it also works....it just doesnt work by the controls......like i said theres 12v there when i have the controls in the off position but as soon as i turn it on i loose all my power going to the resistor...which in turn doesnt go to the motor either...its got me but i cant take it to ford and pay another 68 dollars for them to tell me they dont know AGAIN!!!!

If you know the motor is good and you know the resistor is good... that leaves 2 things. Either you don't have a good ground, or your switch is bad.

Use a length of spare wire to create a new ground lead. If It works, then you will know something is wrong with the old one.

ALSO if i jump the springs on the resistor it also works
Can I ask what you mean by 'springs on the resistor'? Resistors don't have springs but I know that on the later Escort models, the resistor bank incorporates a thermal trip device, which would probably be a bi-metallic link which would indeed 'spring' open in the event that it overheated - is that what you're referring to?

If that is what you mean, and if you bypass it with a jumper, does the speed selector switch then function normally? If so then it would suggest that too much current is flowing in the circuit, causing that thermal trip to break the circuit - either that or the thermal trip device itself is just plain faulty.

I have some data for the '95 Escorts and they didn't have the thermal cutout device within the resistor bank but I know it was introduced on later models and you may have taken the replacement off a late model eh, and fitted it to your '94?

There were a few threads regarding faulty blower motors a little while ago during the winter - I seem to recall being involved in most of them so if you click on my profile and check the list of my previous posts it should lead you to those threads, some of which may be helpful. I posted diagrams for the '95 blower motor circuit in some of them, although you will already have that in your Chilton manual, I expect.

Keep in mind that the blower circuit works by having 12V constantly supplied, and switching only the ground, through the different resistances.
