Re: no air con
there is a wire supposed to be connected to this...it won't be far away....ford don't allow exhorbitant lengths on thier wiring.
Find it and plug it in......should work again
the fact it is covered in electrical tape suggest someone has knackered it some how.
When you find the loose wire, once plugged and tested, retape both together properly so they don't come apart again.
If you are unsure of the wires correct colour, you are welcome to call me during business hours, and i can look up the correct colour for you...FREE!!!!!
