If it is not blowing at all your problem is with the fan. It is mounted up under the passenger side. Typically about 6 screws hold on the cover and the fan is right under it. Pretty easy fix. When the fan is out I would test it first....after thought here...did you check the fuses?
If not the switch, you need to check vacuum lines near the firewall inside the engine compartment and under the dash. Just in case. I had problems with mine blowing only through the defrost because of a broke vacuum line. Good luck
hi ,look under your dash near the blower and find a 4 or 5 wire plug going in near the blower,unplug it and remove the screws holding it in place ,pull it out ,it will be about half a cigarette packet in size when youve got it out in your hand ,this is most likely your problem part ,its a heater resistor ,it controls your fan speeds,it should be a white chalky resistor or an alloy heat sink type ,they come in 2 ways as i've stated,phone a ford specialist junkyard or auto wrecker or a new ford dealer and give them the part number it has on it and your thunderbird specs or ID numbers and you should be able to locate a replacement without too much bother .
THANK YOU for using FixYa
Check to see if the air is coming out of the defrost vents up on top of your dash...by the windshield. If this is the case...you have a vacuum line that has either come loose under the dash....or....the vacuum controller located behind the AC/Heat controller is not functioning properly. ( Tip....Vacuum is what actuates the "doors" inside your AC/Heat plenum...directing airflow straight out front vents...up to the defrost....and down to the heat.....
Try to post back and let me know If I helped you solve your problem. It will help me with my rating....! Thanks
One of your intake manifold gaskets went bad and it is sucking in air where it should'nt be. This problem is very common on this motor. I'm 100% sure that is what it is. But no ofense if you can't figure out how to get your radiator cap off , then this job is probably a little much for you.
No heat is often a symptom of low coolant, usually followed by overheat. There are other controls that regulate heater, but right now, re-fill the cooling system with engine running and heater on high, then check for leaks (coolant you lost went somewhere...you need to determine where) Low coolant will damage your engine. Take care of that first, then if heater still does not work, then do diagnosis on that. (if you loose the engine heat won't matter, will it!)
I think you're right that it is the blower fan. It could be a bad connection on it - that will work when it's hot enough to dry it out, or it may be worn out or sticky.
It needs investigating anyway.
You could first try putting 12V across it to see if it is an electrical issue, or rotating it by hand when cool to see if it is siezing.
Sometimes replacement is needed, but could also be just a bad connection.
