Question about Ford Escort

1 Answer

1995 heater blower motor: someone has replaced it before my sister bought it. The problem is it is wired incorrectly, the blower runs only on high continuously no mater where the fan speed switch is located. Upon inspection it aperes that someone wired it straight to hot. (always on) I'm not sure how to wire it, and I think the resistor is not working. I want to know where the hot wire goes and where the two wires from the blower go. The black is obviously ground. It has a 1 wire plug going into the resistor and a 4 wire coming out. The blue single has been cut and is loose. Help I am not so hot at wiring. Thanks kn

Since its presently working, don't mess with it yet. You can put a toggle switch in between so you can turn it on and off (you can even mount it under the dash). Get a good wiring diagram and use it to make sense of what you have.(Chilton makes a good diagram book which can sometimes be found in the library) I would not rely on Haynes for this,,, I've seen their diagrams and even with 30yrs in the business, I can't make heads or tails out of their stuff over 90% of the time!!)
Likely, there was a problem in the system to start with and the previous owner opted to just hot wire it rather than repair it. Therefore your problem is not only locating and re-connecting stuff, but figuring out what the other guy either didn't want to fix or couldn't figure out himself! Take your time with this and you can figure it out!!! Though this may not qualify as a "solution" it will help get you pointed in the right direction!
Good luck

HEATER FAN DOES NOT RUN. HOW CAN I CHANGE THE HEATER FAN OR IS IT THE MOTOR. DOES RUN FOR A WHILE WHEN I HIT THE DASH.


I would venture to say that if you hit the dash and the motor started running then the problem would be in the heater control assembly mounted in the dash, like bad wire to Heater switch connection. A bad connection can jenerate a lot of heat and start melting things unless you find the problem soon enough. The switch may already be damaged inspect switches and wireing for any vissible damage and replace as required. However if everything looks ok with the heater control assembly, Their are a few more things you can check to be sure of before relpacing the heater blower motor. Turn the heater controles to the high heat and fan on high as well, settings and remove the heater blower motor pig tail and check to see if power is getting to the motor,( use a 12 volt test light at the wire harness side of this connection ) also check for power going to and leaving the blower motor resistor assembly ( mounted to the side or top of the blower motor housing ). If so equipped. If you find no power getting to the motor at this point then you will half to start working your way back through the wireing towords the heater controles until you find the problem. Using your test light. Now if you did have power going to the motor then replace the motor. Good Luck From Ernie @ RedDeer, Alberta, Canada.

Never just replace any item because someone suggested it may have failed. Before replacing anything, you need to check each item for any signs it's bad. In addition to what I mentioned, the blower motor itself can also cause a problem if it is worn out and is drawing too much amperage to operate. If the blower makes any noise or the wiring becomes warmer than it should be after replacing any damaged parts, look at the motor. Bad motor ground can cause problems as well so check that too.

Blower motor resistor


The blower motor resistor is located near the blower motor. It is held in place by 2 screws, and has a wire clip connected to it. Very simple fix.

I hope this helps you, and I wish you luck on your repair.
