    hi

    my mate has got in her escort last night and tried to turn the heater on to clear the windscreen and nothing is coming out, totally dead nothing at all, ive checked all the fuses this morning and they are all fine, none blown.
    next i wanted to check a relay, so just want to know how to drop the fuse box to check the relays, ive looked at the ones under the bonnet in the little holder thing and they are all ok.
    or if anyone has had this problem and knows what it is please please please help?? :D

    any sugestions would be greatfully recieved

    thanks laura

    welcome aboard laura ;)


    year and model please. if u pull the blower motor out (it's located under the dashboard on the passenger's side) u will see that it has a resistor at the very top (close to the electrical harness) that likes to burn up. all u need to do is replace it

    we here are primarily a US escort group.. so our knowledge of the UK Mk. series is vauge at best.

    however, it should be standard procedures to remove the blower motor, i.e not hard.

    once removed, i would use test leads to apply 12v directly to the motor. if nothing happens... or nothing proper anyways, the motor is faulty.

    Two years ago, i had same problem. i changed Blower motor resistor. The problem was gone. if you want to, change motor also, because the blower might be seized.

    Mine had the problem a while back. Motor turned out to be fine. The power plug that goes fromt he motor to the mount was too loose to stay connected. Little tape and no more problems. 8)

    My blower quit working in my 2002 zx2. I pulled out the blower and tested it and it worked. I replaced the resistor and that did nothing. I swapped the 30amp breakers around, no luck. I have ordered a new control switch, hopefully that will do the trick, if not I'm lost.

    The switch did the trick. I need to become a better troubleshooter instead of just trial and error. According to some people I talked to, when the resistor goes bad the fan will still work on a setting or two. When the switch or the fan itself goes bad it won't work at all. At least I was smart enough to test the fan before I bought a new one. The resistor cost $20 and the switch cost $10. Much cheaper than going to the shop.
