Check relays (usually un.derhood) first See owner manual for location. Then check engine coolant temperature sensor. If it's not providing high temp signal, the fans won't come on. However, the fan usually comes on when a/c is engaged. Leaing towards relays

05 land rover freelander. When turn on ac, high speed fan will not turn.replace the engine coolant temperature sensor. I unplug the switch of the fan and jumped it to the battery high speed came on.


Check the fuses first, swap relays. If that doesn't work. Takes a scanner to see what is not working. If the PCM is getting the signal, then look to the wiring to the fuse panel, to the relays. Cold be the relay/fuse panel.

How long for the ac fan to start working? Ive noticed that the fan does not work when i turn the ac on, can this cause my car to overheat. I check the temp and coolant liquid both seems fine.


the ac fan starts as soon as the ac is switched on
the fan is provide cooling of the condenser before the radiator to prevent high head pressures in the ac compressor
it is the fan at the front of the car mand does not affect engine temp
there is a radiator fan between the engine and the radiator that will not start until the coolant temperature reaches a set temp at which point the ECM switches that fan on
if that fan is not working when the engine is hot , check for fan, coolant temperature sensor switch , fan relay, fuses or problem ECM

Why do my fans not come on when cooling


The easiest way to tell if the fans work is to put your AC on max, even if it does not work, both your fans should turn on as long as the vehicle is running. if they do not turn on, check the fuses first, then the fan relays, you can usually swap the horn relay to see if they come on, if you still do not see the fans working, they may need to be replaced, the thermal switch is bypassed while the AC is on max so if the fans come on then, but not when engine gets hot, it may require replacement,
note: if both fans work during ac max operation all the fuses and relays in there circuit are working and need no attention

Cooling fans will not run


By that year they should be electrically driven. Check your cooling fan relay, RDI fuse, and coolant temperature switch. See here p261

My 2000 honda crv is overheating there are 2 fans and neither seems to come on


One fan should come on when the A/c is turn on. The other fan Will be the primary radiator cooling fan. This fan is controlled by a coolant temperature switch, a relay and fuse. Once the coolant temp, reaches 186 degs. the fan should come on. So you have to check the fuses for a burnt fuse, then you can check the coolant switch by un-pluging it and making a jump in the wiring with a paper clip and stick it into the connection. That should force the fan on. Hope this helps FixYa up.

2005 equinox ac fan only works at low speed. I just had it flushed and coolant added last year


There are two relays for the fans. One is a low speed relay and the other is a high speed relay. There are also fuses for the fans high speed and low. Take the cover off or the under hood fuse box and on the inside of the cover it will give a diagram of the fuses and relays. Try swapping the relays with something else and see if the fans go to high when you turn on the A/C as it always should. Sound like a bad High Speed Fan Relay to me but check it out.

Either radiator fan switch or AC system fan activate relay. Check fan switch or look for AC fan motor fuse. Wiring diagram would help.
