1997 buick skylark temperature sensor location

The radiator-A/C fan works sporadically on the car. Sometimes it starts and turns but it doesn't sound or feel to be as strong as expected. It stays on just a few seconds then slows and stops. It doesn't shut off immediately, just gets slower and finally stops. As soon as it stops, I can 'jump start' it again by pushing the blade with my finger and the fan will start up again, pick up a little speed, then slow and stop again. The car will overheat if driven in stop and go traffic for awhile, and the A/C gets warm at red lights. To test the fan's motor, I disconnected the plug and powered it using a 12V motorcycle battery and the fan is very strong (like how it should be). Is this problem caused by the temperature sensor, the relay, or is the fan speed for this model car also controlled by the high pressure switch in the A/C system? Thank you

The radiator fan gets the power from a relay that is energized by a signal from the ECM that in turn gets a report from the coolant temperature sensor
AT this point I would be thinking that there is considerable resistance in the relay
you say the fan works a bit so the temp sensor is reporting toe the ECM which is turning the relay on but power is low from there
replace the fan relay and see if the situation improves
you can test that theory by putting a meter across the wires to the fan when it should be working and reading the voltage available to the fan
if it is not 12 volts or better( 13.2-14 volts) it is the relay

Testimonial: "Thank you for taking the time to answer my query. The car was totaled in an accident last year. I did track it down myself, and it was very oddly the fan itself. When I had disconnected the fan and attached a separate 12V battery, the fan worked, until I placed a piece of cardboard close enough to replicate the air resistance (slight vacuum state) caused by the radiator and A/C radiator being in front of the fan. It stopped working. I took the cardboard away and it started up again. This is the strangest case I've come across in all my years. Stranger still, is that I posted this at least 2 years ago, but under my post I just saw that it says I posted this on March 13th of this year. How can that be? Unless Fixya is recycling old questions. I'm sorry it did not show the correct posting date. It would have saved you from taking your valuable time to reply to me. Regards, Dave"

SOURCE: Radiator Electric Fan Motor on a 2003 Buick Century won't come on when temp gets high

I have a 1997 Buick Century with the same problem. Both my fans work if the A/C is
on as they should. If your turn off the A/C the passanger side fan will not come on
and at an idle the coolant in the radiator will boil, you can hear it in the overflow tank.
If you are driving there is enough air flow thru the radiator that the coolant doesn't
boil and the car doesn't overheat. I have replace the water pump, the thermostat.
and the ETS or engine temperature sensor mounted just above the thermostat in
the thernostat housing, to no avail, I still have the same problem. The only other
thing is the coolant level sensor in the radiator, which I haven't replace yet due
to the fact you have to pull the radiator in order to replace it, which is a major
undertaking. I have a low coolant indicator on all the time on the dash so I have
a pretty good idea the coolanat level sensor is bad. The coolant level is not low
so that sensor is not working as it should. I hope this may help with your problem.
To test you fan raise the hood when it is cold and top off the radiator and fill the
overflow tank to the cold mark. Start the car and let it idle with the A/C off and
see if the drivers side fans comes on. It will have to get to operating temp
before the fan will come on. If it doesn't come on replace the radiator low coolant
sensor on the passanger side of the radiator. If that doesn't fix the problem
replace the thermostat and the Engine Temperature Sensor at the thermostat
housing with an A/C Delco Engine Temperature Sensor. Good Luck..

SOURCE: ac fan won't turn off

In my 2001 Town and Country without automatic temperature control, my heater/AC blower suddenly worked only when set on high. Usually, that problem is your blower resistor pack.

I had to search for the one in my van since the parts man wasn’t sure where it was except that he thought it was in the dash somewhere. (In some other vans it was under the hood.) My Haynes manual didn’t have anything on it except a picture showing it with the blower. I found it directly behind the glove compartment. Very easy to get to once you know where it is.

The glove box can be lowered all the way out of the way just by pulling in the sides so the rubber stoppers come out toward you. The sides bend easily to allow that.

The glove box being out reveals the resistor in the heating duct right in front of you. Just remove the two sets of wires and two bolts (10mm socket, I think) and the resistor pack slides right out. Then bolt in the new one an plug the wires back in (they only fit in one way). Fold the glove box back up and press the stops in to get them back in place and you are done.

The resistor pack only cost $12 and change at my dealer. It is part number 1-04885583AB which was a replacement for the same number with AA at the end, so I’m guessing they had a lot of trouble with the AAs and so made a better AB.

Last Winter my heater blower fan worked only on High. I changed the front heater/AC blower resistor pack and was surprised at how easy it is, but I had to figure it out for myself since my Dealer's parts guy was no help as to where the part lived and my Haynes manual was just plain wrong. This was on a 2001 T+C. I'd be very surprised if the 2001 Caravan was any different. Don't know what other year vans would be the same. I do know some earlier generations had this resistor under the hood and Haynes had is with the blower sort of behind the instrument cluster.

SOURCE: I have a 92 Honda accord Automatic Ex, the d4

That is a fault indication for your transmission. I am not positive but I think that indicates a fault in your forth gear solenoid. Your transmission is not going to last very long driving it like that. When you stomp on the gas and it does not accelerate, your clutch discs are slipping and burning. It won't take much of that to ruin them. You may want to take it to a good Honda transmission place. I don't know about the older Hondas, but the newer ones don't have any provision for removing a pan and working on them. They don't even have a line replacable filter.
Check your transmission fluid dipstick. If its not a nice "bright" red color, you are probably burning up your clutches. The darker the fluid, the more contaminated it is.

1995 Buick Skylark, where is the box with the radiator fan relay in it located?


4d6d3003-b7cd-4c62-a0d4-47967f888842.gifHere is where most of your relays are, there is another relay box located inside the car on the passenger side under the dash. Sometimes youll have to take the glove box out to find the second relay box. This should have a cover on it sense most people do not know of this relay box its usually untouched. The cover will tell you what relay does what. But here is a pic with the relay center under the hood and should help you out.

1996 buick skylark fan operatiion - How to test it?


Take out the temperture sensor switch and put it into very hot water to see if it works. Plug the hole with something to stop losing water. If the fan doesn't work put some voltage on the motor and try that. If that doesn't work it is the fan motor. If it does then it is a faulty switch.

The radiator fan is working fine but the temperature sensor i dont know its locationmy car start overheating sometimes i need help.


The best way to get the exact location for the Temp sensor would be the Haynes Repair manual. As far as your overheating issue goes I would replace the Thermostat and see if that resolves the issue. Make sure the radiator has the correct amount of antifreeze in it.

The problem is a bad ambient air temp sensor or a broken wire to that sensor. The sensor usually is located in the front of the engine bay on the support for hood latch, between the outer grill and the radiator/condensor assemblies.
