1996 Ford Thunderbird Heater and AC Blower not getting voltage.
hello and welcome to Just Answer!

is your thunderbird equipped with automatic temperature control?
Customer: replied 7 years ago.

It has three knobs: Blower speed, Temperture adjust, and ON/OFFVent Direction with AC.

There are no digital displays and not push buttons.

ok, that's manual. do you have a test light or volt meter?
Customer: replied 7 years ago.
Yes, I have a voltmeter.
ok great. check for 12 volts at the brown/orange wire at the back of the function selector switch. should be pin 4. If you have no power, you will need to locate the inline fuse loceted near the underdash fuse block.


check the 30 amp fuse. If blown, replace and recheck operation.

If you have 12 volts let me know and we will proceed. I am sending this as an answer incase this solves the problem. rest assurred if not, we will continue until we find the problem.

Checked pin 4 and has no voltage. Couldn't find fuse near fuse block.

where abouts is this fuse?

it's taped to the harness. it can be a real pain to find. I don't know why they did that, probably forgot to put a fuse for the blower in the fuse block and this was an after thought.... anyways it should be very close to the interior fuse panel mabye to the right of the fuse panel. I am looking for other pictures of it but cant find any
