Hi Guys,

My Climate control is going crazy.

When the ingnition is switched on and engine running, the fan will work in Auto or Manual for approx. 15/20 secs then stop.

The display can be altered to do what you wish with Temperature, Up/Down/Sideways for the vents, Auto/Manual and Fan speed etc. but the fan will not work.




The display shows the scale going up and downon its own, although the fan is not working.

Its the same Winter or Summer.

Just a thought, would this be a faulty air temp sensor if fitted, if so where would I find it.

Any clues, thanks

Another thing I've noticed,

If I just turn the ignition on, the heater fan will run forever more but as soon as the engine is started the fan will only run for approx. 15/20 seconds.

Any clues

Thanks

Sounds like a bad fan regulator. Let us know if you get any codes.

Ok The figures shown below are taken from the test.

1) The figures shown are with just the ignition turned on and where I can alter the fan speed as I wish and the fan continues to run until the engine is started.

2) The figures shown in brackets are with the engine running and where the fan does not run at all apart from the first 19/15secs. Although the scale shows the fan running up and down (as shown in item 19), its not. Just the sacle goes up and down.

If anyone can make any sense of these figures as what the problem is. Please help me.

Sorry it taken so long to get this on the site, I tried and paste the results above from 'Word' but no joy. and had to do it again online.

I take it then, no one knows what all these figures from the test mean.

I'll have to find another way to find out.
