overheated (i think bad therm) removed it and now only gets up to 110 degrees in 10 mile drive!
BUT can't shut off check eng lite and cooling fan runs all the time.
Been to 3 different places but code scanner won't work in OBD2 plug and we tried OBD1 plug under hood that has a cover that says "ABS TEST PLUG"
Tried disconnect battery overnight to no use!
HELP
Thanks

-The fans are controlled by a coolant temp sensor in the intake manifold. There are 2, 1 only goes to the guage in the car and is basically a glorified idiot light, the other sensor goes to the computer and is used to turn on and off the fans (through the CCRM), and make fuel ratio calculations.
-If you have the a/c or defroster on the hi speed rad fan will also be on.
-By removing the thermostat, the coolant flow isn't regulated. It will take longer to warm up and won't cool as good either because the coolant doesn't stay in the rad long enough to transfer any heat. Put the thermostat back in.
- You can read the codes yourself with a paperclip. The instructions are in your Haynes/Chilton manual. Or buy a Ford OBD1 reader. They're cheap. The OBD test port under the dash doesn't work for codes on 94-95GT's.
The parts stores around me can't read OBD1 cars either.
