Hi all, no life at all in the unit.
No lights on the demist button, no blower, nothing.
Unit just seems dead.

Would anyone have a step by step fault finding process please.

The air con has never worked, and was aware of this when I bought the car. The seller said at the time that they are very problematic. The heater and demist always worked really well.

Just an aside, the front of the unit looks slightly different to all the ones I have seen images of on the internet while researching the problem.

Thank you 😘

Bervill FX have a step by step guide on their home page, the unit is called CCU if You want to do a search here!

Thanks for the reference Railmaster.
Heidi, check fuses 1, 28 and 17. How is your CCU different from others? Any pictures?
Cheers,

Are You sure that Your car have an AC? Maybe it doesn't and that could be the reason Your HVAC unit looks different! Or it could be a unit for a car without AC.

Thanks for the quick replies,

I shall post a photo of the unit soon as I get home, it's raining here and even if I wanted to take her out, it's too difficult driving when I can't stop the windows steaming up!!!

Are these fuses all under the bonnet in the same place (or hood or whatever it's called depending where you're from)?
I mean like in the footwell etc???

Railmaster.

Take a picture of Your engine bay aswell so We can see if there is an AC compressor installed! The fusebox is located in the front luggage compartment.

All the mentioned fuses are in the main fuse box in the luggage compartment.

Ok this is the unit, and looking at it I would say it doesn't have air con.
I just assumed it had air con as the guy who sold it specifically said it wasn't working????

Also checked the 3 fuses, in fact all the fuses

This is a normal non-A/C Climate Control Unit.
If all fuses are OK, you have to start digging with a voltmeter to find out if all the power supplies are present on the CCU harness connectors. You'll need some electric skills to do this. If all power feeds are OK, there's probably an internal fault in the unit, which is no problem to fix.

I thought the car had A/C, is there a compressor on the engine? Is the CCU original?

Railmaster.

As I said! Show us the engine!
