Hi folks

Can anyone help? My heater doesnt work (hot or cold) on my mk3 Orion (mk5 Escort).

Ive removed dash panel to reveal the multiplug in the back of the heater controls. There is 12v there so that eliminates the fusebox problem, yeah?.So ive removed scuttle panel and wiper mechanism to reveal heater blower. I got 10v (?) on one of the pins but nothing on anything else. Although should I have tried when ive put the heater on different settings to see if other pins work? People say to run wires from the batteru to the blower but wasnt sure whether I should connect positive to the single plug or multiplug? Don't want to break anything!!

Grateful for any advice folks??

 

mk5s used to suffer bad with electrical faults, and the most common was a cracked fusebox circuit board, but saying that it could be a heater resistor or the actual fan motor so trying to power up the motor direct for testing purposes is a option but not a option for anyone without electrical know how
