Fan runs constantly (1989 200 qa)

[Shaun Folkerts]

This figures. The day before I was to drive back east with this car!
Went out to run some last minute errands yesterday, 107 degrees out, fan
came on, no problems. Sat with it in the parking lot, opened the hood,
left car running to cool the turbo and wait for fan to turn off. Half
hour later, I was melting, battery was near dead, and the fan was still
running. Gave up and drove back to the hotel. Fan on the whole time.
Went inside to cool off, came out twenty minutes later, fan still
running. Eventually pulled the battery cable and gave up for the day.
This morning, nice and cool outside (relatively speaking, this is
Nevada). Returned to the car and reattached the battery cable. Damned
fan still runs constantly!!!
What can I do to regain control over this F'in' fan, because right now
it and this car have me by the short hairs.
Already pulled relays, fuses, etc. that I thought may be related - there
appears to be no way to kill it without disconnecting the battery. To
make it worse, I need the fan to work due to the high temperatures out
here and on the way back to PA, so I can't just go cut the wires - and,
man, am I tempted!
Just went outside and tried to run the car a bit, to see if it would
shut off the fan. Yeah, right.
Basically, the bottom line is that if the battery is connected, the fan
runs. Period. What can I do to fix this car (again...sigh...)???
Thanks.
