The fan on my 1998 polo 1.4 doesnt kick in wen the engine gets hot, i have tried bridging the plug for the thermo switch with no results. there is power down to the plug and all fuses seem ok. im not sure if there are some other fuses for the high and low speed on the fan or if im looking at a broken wire. can any1 help cheerz

SOURCE: no low speed heater fan, only high speed works

BLOWER MOTOR RESISTOR IS BAD . HI SPEED IS DIRECT POWER BUT ALL OTHERS GO THROUGH RESISTOR

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

SOURCE: car overheating, fan not kicking in, changed fan

REPLACE THE THERMOSTAT.FAN NOT KICKING IN CHECK FAN FUSE AND RELAY.ALSO BAD COOLANT TEMPERATURE SENSOR WILL CAUSE NO FAN OPERATION IF FAULTY.

Yes! I almost sure
I know what is grounding or Why????
A/C compressor COIL is broken!
As this coil works with static energy, once broken, the voltage gets through the compressor body.
I think that's most posible cause. Hope this helps and good luck!

firstly i think you have overcharged the Ac system as the most it should hold is 650 grms for this system on this model ,if too much gas it will click in and out and slow the engine down ,as for the gauge readings then renew the sensor its on the housing at the front in the plastic housing ,depending on year and model this is where most are ,but some later models have a sensor at the back of the head left side from front
