I have this table which would suggest E4 and E0 is a front temp sensor failure as they both relate to this.

Smokey - thanks again. This all looks like it will be a great help. Thank you.

So....... just before I start to remove all the dash etc......... Is it likely to be a fuse that's stopped the blowers from working? If its a possibility can anyone tell me which fuse it would be?

Thanks

Have you had the fan out to see if it still turns, it's about 10 minutes work and requires no dismantling of the dash, a multimeter on the fan power connection would be worth doing as well.

Right.... I've had the fan out and a multimeter on the connector and thee is definitely power coming to the fan unit. How much power should there be to drive the fan.... Amps or volts........

I've tested the fan unit on my 12v battery charger and it works fine.

I've also had the dash off and the internal temperature sensor fan was sh!tted up. I've cleaned that and it seems ok.... But still getting e4 error. So could still be the sensor that is the problem.....

Strange that the multimeter is showing some power coming through but not spinning fan!!!???

Help please!!!!????? I'm more confused now than before!

Hi Mark

Would you mind if I take you up on your offer please?

Are you around one evening in the week so that I could swing by?

Cheers

The voltage on the fan plug will vary with the speed selected, but it should be 12v at max speed.

Have you fitted the new external temp sensor.

Not had chance yet.... Was taking your advice and checking the fan and internal sensor first.

no probs, but you should find out the colour code/wires for the ext temp sens also as I may be able to get you a piece of loom if your is missing.

I think that front bumper may be coming off again!
