Have 1990 ford tempo GL with cooling fan that won't start ,Had thought it
was the sensors .Changed bolh of them and still wont start fan at higher
than normal temps .Tested the fan and it runs ,My next question is where do
they put the relay for the Fan ? And about how much would that fix be
.Thanks Chevy -man
before you buy anymore unneeded parts. If you have the know-how to test the
fan, you should be able to diagnos it with the aid of a book/wiring
diagrams. Relays arent very expensive(unless you dont need them)

With the key on, hook a jumper wire between the 2 connections on the
temperature switch on the thermostat housing. This should cause the relay to
I have had Fords of this era where you can hear the relay clicking under the
hood. Others seem to click inside.
In any case, if it's not clicking, then you can be fairly certain that it IS
the relay that's causing the trouble.
If your temp switch is working you can rig up any ol' generic relay (rated
at least 30 amps) to switch the fan on and off. That would save you having
to locate the factory relay if the click test doesn't work.
if the relay or a wire to or from the relay is shot... it is cheaper and
quicker my way... and yes it is a cobble job.. its a 1990 car.. why dump any
money into it!
Get a cheap toggle switch somewhere and 10 ft of wire.. 5 dollars..
thats what i would do... if it were a 2002 model i would fix it right and
spend the extra money. the car may only last another 1/2 year who knows..
damn thing prolly dont need a fan anyway... as long as he isnt sitting
idling while its warm out.
I ran wires though my door.... never had a problem.. that was on a 93 dodge
spriit... i ran the wires to the fog lights... up to the top of the engine
compartment.. then down where the door opens./.. i checked for
clearences... did not have to use a drill at all.
It is a slop job but the car is old... it may die tomarrow or last a
year... if it were me honestly... i wouldnt bother with anything unless
you sit in a lot of traffic on hot hot hot days
sure make fun i dont care... but im the best at rigging stuff to get me
by... why spend money when you can rig something a lot cheaper...
i do what i want to my cars... i made suggestions for somebody else to try
that if they dont want to they dont have to.
Why pay some mechanic to do 10 minutes worth of work? and pay them for an
hour? why buy parts that cost 100 dollars where u can buy something else
im good with tools... there are times when i fix things properly... but
when it comes to rigging and saving a few bucks im good at that too.
out and starts a fire. The first thing you'll do is file an insurance claim
and then we all have to pay for your stupidity. Why anyone would cobble
something together when the right fix is so easy escapes me.
relay for the fan(and alot of other things all in one box ) is located
right under the plastic panel over the radiator.. it cost about $150 at
auto zone, and probalby is not the problem with your car.... but you can
take off the wires relay and make sure its clean and put it back on and
then take off the relay box and scratch where its attached to the car to
make sure it get a good ground.....you probably gonna need the shop
manual and electrical manual from Helm, Inc..
www.helminc.com they cost about $65 for the shop manual and $35 for
the electrical manual.... thats what i needed to get my electrical
system working on a taurus...and thats with 40 yrs. of working on cars..
if i was just starting then i probably would not have fixed it not being
familar with troubleshooting.....
