car reg PJ07EFU

Not tested for power to heater resiistior unit Mike this is my daughters car.

My son in laws father says he as tested the actuall motor itself & this is possitive .

The heater fan motor stopped working intermitantly, now & again it would work. Last time it worked for about three months solid, then just stopped.

We have bought a new relay switch fitted this & nothing works regarding the blower.This is me grabbing at straws about the relay switch useing q 7 a on google. Hope you can help.

Regards Pete

Hello again Peter -

Ok - I need you to check on the fuses - re check.

Your vehicle range had slight changes in 07 so there are two types of fuse box in the engine bay - two different one so I'll tell you both.

Check if have a fuse number 54 - a 7.5 amp

Also - check Fuse no. 28 - a 40 amp

And check Fuse 30 - a 7.5 amp.

That covers both types - all those are for the heater system.

I dont see in the diagrams, any relay for the system.

If its not a fuse - and its not the resistor unit - or the blower motor or the switch - it then has to be a wiring / connection issue in the circuit that will need physical tracing with a test lamp / meter -

But work through as above checking on those fuses first . Let me know how you go.

By all means get back to me if you need on this..
