Please can you give as much detail as possible about the problem and vehicle, and have you done basic checks such as checking fuses etc

A nice hello goes a long way as well

Sorry no hello, wife panicking on road and ice expected so rushed straight to asking for help. Thanks for replying ad hello to everyone on this forum.

i have asked her to check wires etc but that is all. I am now telling her to get hoe and I can then check out Fuses etc. Car working fine just no air con and heating etc.

No problem, i know the feeling when panic sets in haha!

I'm not sure if it affects 807's but the resistor/loom normally goes on the 307

But if you get as much info as possible i'm sure someone will have an idea

Stubbo, its poor contacts on the fan that is causing the problem. There is a 50 amp supply cable from the engine fuse box direct to the fan with a further small connection from the ac panel that controls the solid state resistor block in the fan assembly.
You need to remove the glovebox (assuming 807 is UK RHD) and pull the main terminal block connector to the fan off and on to try and clean the connection. If this doesn't work you need to unbolt and remove the fan and carefully take it apart as there are 2 further 50 amp spade connections inside the fan between the resistor block and motor either of which could be the cause of the trouble.
Cleaning both worked for me. Good luck, wyn b
