Question about 2001 Ford Mustang

1 Answer

Heater not working properly

I have a 2001 Ford Mustang and the heater/air only works on the high setting. So, it's either have the heat on full blast or turn it down one time and it's like I've completely turned the heat off. My Dad can't seem to get the dash off to take a look at it.. My window was messed up and it took him a while to get the door off.
Any ideas?

Over top of the blower motor you will see a 4 wire connector hooking up to what is called the blower motor resistor,the wire colors will be OG/BK,LG/WH,YE/RD,BK. It will be held on by 2 clips or screws,this is what is bad and needs to be replaced.

Most likly this van has seperate controls for driver and passenger heat and ac controls.If its blowing hot air your heat is working.These controls operate differant dampers that are electonicly controlled.If the dials arent working they would cause this problem.

hi from uk the problem your symptoms describe esecially the bubbles that are appearing in the coolant header tank would suggest that the poor heat in car is due to air locking in the heater and this is most probaby the air bubbles you see in head tank are also finding their way into heater matrix via heater hoses may i suggest that asap you visit garage for a cooling system pressure test because theseair bubbles should not be appearing and is a sgn that you may have a cylinder head gasket in early stage of failure and what these bubbles are is compression in cylinder/s is leaking via gasket into the coolant system and emmiting in the head tank however i do say early sign so a compression test on cooling system will confirm whether or not ? considering cars age? it is not uncommon especially if high milage or any history in past of overheating ? hope this helps

Engine heats as normal both heater hoses hot at firewall heater blower works but no heat


I have a 70 mustang that did that. My problem was the core was clogge and the water couldnt circulate through properly. I took both hoses loose and sprayed the garden hose through each one to clean out the system. took about 10 minutes but my heater started blowing hotter air. you can use a spray gun on the end of the water hose when you point it in the heater hose. dont use a high pressure hose, just a garen hose with a sprayer on it.

Heat levels..


need new technician.if the blower motor works even with only one speed than the blower motor works and did not need replacement.sounds like blower motor resistor or resistor wiring,when there is a problem with the resistor or wiring you will only have one speed,this way you atleast have heat.so if your tech replaced the blower motor when it worked and did not need replacement then it sounds like he is just throwing parts at it,you have to wonder if he really checked anything.have the resistor and wiring checked and if ok then check the heater control head and wiring.

A/C is on and rear heater blows full blast from vent on the sliding doors


I had the same problem and the gear box that opens and closes the valve for the water flow through the heater core was stripped. I had it replaced because it is a bear to get to. Hope this helps.
