Topic: Heater blower motor

[65springtime]

I do not need one at this time but if I ever do need a new blower motor for heat, do you take the old motor off from inside under the dash or the engine compartment?

To remove the heater blower moter on a 64 thru 68 (67 and 68 with air is a bit more complicated), you need to remove the entire heater box. Go to the FAQ section and do some reading. The reference is about replacing the core but the motor is simple once you got the heater box out.

I was afraid of that. Seems like they could have put it so you could exchange it from under the hood. Thanks.

Another option if you choose; Go to Mustang Monthly website, they have a great step by step article that will walk you through taking the heater box, core and blower motor out and putting back together.
Be aware it is a project and patience is a must ! That was one of the first projects I tackled when I bought my 67' but once done, well worth the effort. Like a lot of cars domestic or foreign they designed the heater box/core assembly and then built the rest of the car around it.......

Good luck

I still say I do not see why they (Ford) could not have the blower motor mounted on the fire wall? Guess they wanted the dealers to make a little more money when one went south.

Hey, I gotta an idea. Let's move the engine and transmission to the rear - that eliminates any drive shaft problems. Then let's make the engine air cooled - that eliminates the radiator (and associated leaks) and then duct exhaust heated air inside. Make all models either fastbacks or convertibles - that cuts down on body parts. And have them made in Germany - that keeps costs down. We can make them for the people - call them "Volkswagons".

That is part of the fun owning an American classic, Digging into projects and when completed patting yourself on the back and saying "I fixed it myself" !! As long as you are into the heater box you may as well install a new seal kit and replace the heater core as well, that way you won't have to worry about it for a long time. You will know what I mean once the project is under way.

 Honest, I was not trying to start anything...Just did not understand.

I'm glad the heater is not in the engine compartment. The blower motor sticking into the engine compartment provides enough hinderance in the removal (and installing) of the RH exhaust manifold on my 66. The installing part is tomorrow.

65Springtime, We were just monkeying with you. Classic Mustangs are great cars, aside from a few challenging design features ( as are all cars) they are simplistic for the most part to disassemble and reassemble correctly.
An important part of American automotive history, deserving of restoration and enjoyment..

I agree....The 65-66 Mustangs are the easiest classics to work on.  Ever try digging into a '57 Cadillac?   

[65springtime]

Well, mine is still working at this time. But was looking in the engine compartment and could not tell if the fan motor came out from outside or inside the fire wall. It is covered with something like undercoating on the firewall and could not tell.  On the Chevys I had they came out from under the hood off of the fire wall and the fan motor looks just like the one for the Mustangs with the same big lip around it for mounting. But when (and I am sure it will someday) it goes bad, I will go ahead and put in all new parts then. I can feel heat coming in under the dash last summer and did not know if something is wrong with the heater or if the heat is coming from the chrow. I have the fresh air knob shut off. Yes, I have heard these cars are easy to work on. I have been reading a lot about these Mustangs classice since I got this one. I had a 66 convertable back in 85 but traded if for a 1957 Chevy Nomad. My wife and kids (all girls) were not happy with me. They loved that Mustang and thought the Nomad was big and ugly. Later sold the Nomad for only $2,500.00. It was a beautiful car. Hinesite on both.

'57 Cadillac, I think I would rather try that than the new cars of today. Ech!! Glen, You had a '57 Cadillac? Or just using that as an example?

[66GTKFB]

If and when you have to replace the heater core or motor, a couple of points: remove the passenger's seat, it makes the task easier; be careful of the defroster plenum, it's cardboard and fragile; the two slipon the plenum, flexible defroster hoses are also fragile, they can be removed from the car if you take out the speaker grill; the two defroster nozzles are cardboard and also fragile, held in by 2 clips each that almost always are destroyed in the process;  there are press on caps on the control arms on the heater, they are usually not reuseable, but not always needed; get new hoses for your installation, you almost always need to cut them in the engine compartment to remove the box; there is one "hidden" 1/4-14X1 1/4 hex screw (3/8 hex) on the RH side up under the dash in addition to the four stamped nuts in the engine compartment.
I didn't design the parts or installation, I just know how to fix it.

Yeah, I have had a bunch of cars to include the '57 Cadillac,  '56 Pontiac Chieftain, '64 Corvair. etc.

I am sure it would but I have the bench seat in mine. Guess I would have to take out the whole seat. Yep, sounds like changing the motor will be fun. Oh well, I am retired. 

[Jeff1967]

For me the job was my first on my 67' convertible because everything was leaking even the radiator but as I posted earlier once done everything worked like new again. My car is not a daily driver so there was no hurry to get it done. Once I had had enough for a particular day I could walk away and come back fresh to get to the next step.

My car so far has been a two year project as I get extra $$ to work on it,  looking forward to the day she is returned to her former glory

I hear you. I too am not using the Mustang as a daily driver and in no hurry to getting it done but also look forward to the day it is in the same shape as it was (or close to it) coming off the assembly line. As I said "or close to it". But will take time and also as I have the money.
