Hi,
We have a '91 escort with AC and automatic transmission. It seems to
run a bit hot. Is there a way to check if the low speed fan is coming
on? The high speed is coming on when the coolant temp gauge almost
goes to the hot zone.
When AC is turn on, the low speed fan is also on. So I assume it's
not the fan problem. Can I make the low speed fan on by putting a
jumper at fan switch connector? Would this force it to turn on? I'm
also wondering if low speed fan relay is in working order...

Thanks for your help!

It doesn't run hot on highway or when there is enough air flow. When I say hot, I mean the temp guage almost goes out of normal range and goes into hot zone.
In a traffic jam, after a while, it always almost goes into hot zone before the high speed fan turns on. This is why I think something is wrong with the low speed fan. If it were working, the temp shouldn't go that high...

Any thoughts?
Thanks.
