Heaters Only Blowing Hot And Cant Change Where It Blows Out From

[leightonwoody]

i recently changed the coolant in my car and have since noticed that the blower will only blow hot air and only too the windscreen,

the nob that should allow you to change airflow direction, ie floor or vents doesnt seem to work. the 3 buttons for aircon and rear buttons and the other 1 wont come on anymore when pressed the only thing working is the blower speed, the temp gauge stays at 90 and doesnt budge from there

any help

It might be worth giving the details of your car and which fuse you replaced to help other members in future :rolleyes:

dead easy !!! and takes 10 minutes to fix

 

remove the heater control panel, 4 small torx screws behind the front after you have pulled it off, there are 2 wiring loom plugs attached to the rear of it---take them out. make sure the wires are not touching anything, then turn ignition on for 10 seconds then turn it off again.

 

refit the 2 wiring loom plugs, refit the control unit and leave ignition on for 10 seconds then turn it off again.

 

now start the car and it should be working again, temp,direction and rear blower motor---------there is a revised control unit available from ford at a silly price -----------or try my way to fix it for free ??????

 

done mine several times in 8 years of owning the car.

After all the bad weather I would be willing to bet its water in the wiring loom.

Take off the passenger footwell trim and strip back the loom, you should find 3 wires that for some reason Ford saw fit to just tape together. They will be corroded from the water ingress. Strip them back, re-make the connections properly and you should have a working heater panel again.
