Check the two relays in the fuse block under the hood. One is forthe primary and the other your secondary fan. Turn on your AC unit both fans should come on. If not replace the relay. Also you have two temparture sensors that could be faulty.

SOURCE: cooling fans on 2001 chevy malibu will not come on unless ac on

the relays control circuit is grounded by ECM (computer) . to check this make sure the is hot enough for the fans to be commanded on by computer and check to see if you have voltage at relay and it has ground from computer . you may need ECM.
good luck

Where is radiator fan switch on 1998 olds intrigue


You have relays for the cooling fans. Did you check applicable fuses and voltage on fuse circuits? Any applicable trouble codes?
Check the coolant temp sensor. Don't replace anything unless your testing points in that direction.
The low speed fan comes on about 223 degrees F, hi speed about 230 degrees f.
If you turn on the ac, the fan/s may run? On some makes and models, if you unplug the coolant temp sensor, the fan/s may run?

2006 bBuick Lucerne fans doesn't come on unless I unplug the sensor connected to thermostat


If your talking about coolant temp sensor, maybe something wrong with sensor? Any applicable trouble codes? Some of the national brand auto stores will check codes for free.

Some makes and models if you unplug that sensor, there will be a default mode and the computer will turn on radiator fan. If you turn on ac, the fan may run.

Engine cooling fan only works when ac or defrost is on


if engine at long stand still,the engine temperature will rise about 190 degrees the cooling fan suppose to automaticaly turn on when coolant temperature sensor get hot it cause its resistance decrease causing pcm to send power to coolant fan relays and cooling fans, when you turn on AC the cooling fans suppose to turn on to cool down AC CONDENSOR, IF NOT AC WONT WORK COOLING FAN COOLS DOWN REFRIGERANT SO IT CAN RECYCLE THROUGH THE SYSTEM AGAIN.your cooling is suppose to turn on when engine at a sit still if vechicle not moving as coolant temperature rises at a set point the cooling fans will turn on cool down engine.cooling fans dont turn on when you first cold stsrt vechicle unless you have AC SWITCH ON.if cooling fans dont turn on when vechicle at a long stand still or moving along slow traffic.if coolant temperature sensor been replaced and fuses and relays okay have dealership check see if pcm driver circuit working faulty pcm will cause cooling fans not to turn on.

Coolant temp runs hot after about 20 minutes of driving. and when idled. Replaced thermostat looking to replace water pump too?


Your electric fan should come on around 220 degrees or so, if it does not you need to replace the sensor on the left front side of the block. The fan should come on immediately if you have AC and turn it on. If it does not check the relay in the fuse box under the hood, and related fuses. Unplug the electric fan and turn the ac on and check for power. It could be your fan motor quit. Usually if the fan does not come on when the AC is turned on, and it does not come on when car reaches 220 degrees, the motor is most likely the culprit.

My 2005 mustang engine water is overflowing and boiling I've changed the termosthat and cooling sensor as well as the radiator is not clogged up. The fan doesn't kick in unless I turn the ac on any...


the fan not coming on unless you turn the a/c on is a clue.this tells you the fan is working but the coolant sensor for the fan operation may not have been the one you changed(as there is one for the dash gage/light and one for the computer to turn on the fan).also the fan relay may be the problem not turning the fan on without the a/c on.

Odd .
Fan won't come on till like 230 degrees.
Or run a small ground wire from the relay to a switch inside.
