What is your question?
There is a 10 mm nut I took out but there is also a huge slotted 17mm plastic nut mounted to firewall towards the front of car. I have been turning on it forever with a big screw driver, doesn't come off. I need to change the blower motor relay and of course it is all the way in the back. I have copied and pasted a similar thread for detail. Q&A 1999 Ford Escort Question: blower motor relay Question chas1376, 2.0L 4 Cylinder SOHC, Pittsburgh, PA, January 17, 2011, 16:47 Profile_thumbnail Rookie Where would blower motor relay be located?Ford shop manual I have says 30amp fuse is located driveside next to fusebox which I found,however,it does not give location of relay.I get no voltage at motor.Thanks,Chas1376 1 Answer Flag This Follow this Question Answer #1 DaveJHM January 17, 2011, 21:48 Profile_thumbnail Master I think you should focus on the blower motor resistor, which is in line to the blower motor under the passenger side dash. Flag This Like | 2 people like this Reply Visitor, January 18, 2011, 07:46 A schematic of circuit shows wiper fuse(checks good) picks up relay coil,so blower motor circuit starts at 30 amp fuse(checks good),through contacts on relay to motor before resistors or control switch then to ground,I am not getting any voltage to motor which makes me believe motor relay is defective.My manual says relay is locate under driver's side,but I do not see it.Thanks,Chas Flag This Reply DaveJHM, January 18, 2011, 20:36 Profile_thumbnail Master Chas, Begging your pardon -- just that I've seen many Escort/Tracer blower motor resistors fail and melt. To answer your question - there is a relay box up underneath the drivers side dash near the cowl. It houses 6-7 relays. Looks like it's buried up there pretty far. Good luck. Flag This Reply Visitor, January 19, 2011, 09:21 I found it, you are right.It is housed under driver side inside with other relays upside down in white plastic box.Removedtop nut with#10 socket,also attacked with straight screwdriver on inside firewall replaced relay no joy.Going to blower motor right side passenger side and jump out motor.The circuit is 30 amp fuse,relay,motor to control panel including resistor bank.Motor wire blue/black wired to ground should operate motor with ignition switch on.that is my next step.Thanks for the reply,Chas Flag This Reply DaveJHM, January 19, 2011, 20:28 Profile_thumbnail Master Just quickly, have you looked at the resistor and wiring? Your theory of attack all sounds great, but cutting to the chase...if I had to put money on it... Flag This
Thanks, I just actually got in and have the relay in hand, I was able to figure it out! That's what I had been trying, but I was using too big of a screwdriver to pry (the same one used to turn that big nut.) I took a normal size flat screwdriver (of course the nut was all the way loose and just turning at the end of the bolt when I turned it at this point) and got behind the back side of the housing, not on the nut itself, and the whole unit slid off of that bolt that the nut goes on..For the record, the relay was burned at the 87 prong which is the power coming in from the fuse. That might explain why the blower motor would cut in and out. I have changed the resistor and the wires coming in and going out, checked the fuse, and it works intermittently as I turn it off on, etc. so I am hoping this relay is why it is losing power. Off to the store!-Thanks. Update Jan 6-put in a new relay this morning and blower fan worked great on all speeds with no cutting in and out! I ended up changing the resistor, relay, and wiring harnesses on the resistor. There was a little "browning" of the relay plug (the female outlet the relay plugs into), but I am not going to change it out as it looks like more potential trouble than what it is worth. My electrician friend said to just put some dielectric grease in there to keep it connected good and it should be good. I agree, because it works fine and not burned black or melted like the relay itself and the resistor wiring harnesses. My experience/advice as an unskilled 40 year old DIY mechanic is to check relay and resistor and the wiring because it could be both of them that are causing the blower to work intermittently. Get yourself a cheap $5 circuit tester with the light and find the wiring diagram for your vehicle blower motor circuit. With little mechanical experience or ability, I was able to think through this and get it done, thanks to all of the people on the www who share their knowledge and experience! If their is anyone who needs assistance or has question on the 2001 Ford Escort blower motor, relay, or resistor, I can probably help you now!
