Thanks for the tutorial! Had the exact same problem in my '83 GLX 5.0. Just pulled the blower motor today and full of nest. Bought the metal fan from LMR, can't wait to have a functioning HVAC again.
Great tutorial! I'm going to clean out the assembly on the 81' Cobra this weekend. I have a new blower motor but it just doesn't blow very hard. I bet it's full of rats nest just like yours was. Nobody has the fox bodys around here though...a spray bottle with some listerine mix usually takes care of smells...that's what they use to treat fire damaged houses... Thanks for the info!
After seeing the condition of yours, I think a removal and cleaning is instore for mine before even turning it on. Car sat for many years and I know mice were inside my interior. Cowl was not bad but this definitely needs to be done! Thanks for the vid!
Right on! You bet. Yeah, I tried at first to clean from fresh air door and no way you can get all debris out that way. Then I saw how easy it was to remove.
Great video. I have an 89 GT heater never worked and i store it in winter i been looking at how to take the useless stuff i don't need out but everyone assumed i was stupid🤷
Yeah in your case you can drop the entire HVAC unit, if you dont want to use AC or Heat. I have a vid on heater core replacement on the 86 and complete dash removal....if you just want to pull it. Lots of folks do this for their race cars.
Good work! Do you have some sort of diagram of the vacuum lines that run under the dash for the HVAC? I had to put a heater core and evaporator core I mine, but my vacuum lines are all jacked up.
I dont, Im sure the googles has it somewhere. Man, its really pretty easy. Only i source vacuum that goes in from the engine bay feeds it all. The HVAC controls are the only other lines and they are all on a vacuum plug, so unless you pulled each line out, its plug and play. The canister on the blend door also has a connection, and it goes to that hvac plug.
I'm sure you can, but any issues/ major modifications to put an 82 or newer box in the 79?. My AC is busted and parts are impossible to find for that system.
Its in cabin recirc. It opens when on "max-air" so the intake becomes the footwell and recirculates the air to cool it. This is my when putting your AC on MAX it tends to get louder as well.
took my heater blower housing out on my 1991 5.0 Coupe and reinstalled it, now the air blows out of the defrost vent on any setting..how do you fix that?
@@HOUSEOFDULA yess I had to cut both of the plates off on top to get to it all but I'm glad I did find it all but I been doing autobody n paint since 89 so it was cake walk
Could be a number of things. If I had to guess the plastic "tubes" that connect out hvac box to the vents are disconnected/broken. That or the impeller wheel is broken, OR the AC avap clogged, or...vacuum issue, and the door is not actuated, but if this was the case all air defaults to the windshield vents (if HVAC box has no vacuum)
Appreciate it Mike. Yeah that speed switch it also super easy to replace. Never had one melt! Most likely someone had a fuse larger than factory, the impeller hung up and melted that bad boy lol
Man I dont know. Rodents, mice, rats. But your right its all mice not rats lol We say a lot of weird stuff like a "coke" = all soda. We dont say "soda pop", ever.

I have the same issue with my mark vii. I didn't realize that it would come out like that, glad i saw this video.
Thank you! Yessir once I found out I had to share it with others, makes so many things easier.
Thank you for this... found the blockage. Air is blowing again! Subscribed!
Thanks man! and Welcome!

Seriously man, you just saved me. Came back from a trip & mice had taken residence in my Thunderbird Turbo Coupe. Greatly appreciate the video!!!
Nice!!! Love hearing this. Timely too I presume, good luck to you out there.
I have an 88 TC TBird also. Is the process the same ? Being a foxbody car?
Very helpful thank you

Thank you! That was a huge help
Its not only humans that wanna be in a foxbodies, cant blame them
HA exactly. Damn mice, but I admit they respected it. No wire damage and didnt get in interior.
You my friend are my new friend lol I got my son a 1979 mustang cobra
Nice!! Such a cool car. First year fox cobra. Hopefully learn a little here as I work on my 79.

Good tips, also for the blower motor, think about taking them apart and cleaning up and well. Super easy to do and it may save you from buying new.
Great point. This would have been the time to do that and inspect the impeller. Didnt think about serving the blower motor.
Thanks for sharing I'm working on 82 GT t-top and been sitting for while gonna take mine out see 👍
Prob good idea. Otherwise might be a suprise when you turn it on lol
Lmfao 😂 probably
I love this car!!!!!
Thanks for the tutorial
Any time
Great video. Thank you Sir.
Thanks man! This is helpful. My 83 when I put the fan past low. It squeals load. Not sure if it is the motor or fan or both.
Well done 👍

@@HOUSEOFDULA Thanks a million
Nice man, you need to drop a 351 windsor in the 79! Lol
(coyote) ;)
Nice!!!
did you replace the filter part or leave it as is? not sure what that material is besides old
Great info. Are you thinking a Gen. 2 coyote w/ mt 82 swap?
Thats the plan, except I want to go 6R80 with this one.

Do you know the length and size of bolts, I’ve lost my hardware and would like to reinstall my hvac box
I have a 91 fox that already has the a/c deleted. Do I still need the blower motor?
I'm sure you can, but any issues/ major modifications to put an 82 or newer box in the 79?. My AC is busted and parts are impossible to find for that system.
Yessir. At least I know this for the blower motor. This one was out of a 84 up
Did you have to disconnect the battery
You dont have to for this. But if makes you more comfortable it sure wouldn't hurt.
What is the purpose of that flapper plate on the blower? Recirc air? Or Re-Direct air to the footwell? Or something else?
Its in cabin recirc. It opens when on "max-air" so the intake becomes the footwell and recirculates the air to cool it. This is my when putting your AC on MAX it tends to get louder as well.
@@HOUSEOFDULA ah I see now. Thanks.
took my heater blower housing out on my 1991 5.0 Coupe and reinstalled it, now the air blows out of the defrost vent on any setting..how do you fix that?
One of your vacuum doors is probably stuck, check the one behind the radio from the driver side
Or maybe the vacuum line on the box broke when you removed it, the default is the defrost so it could be a vacuum leak
Man I had to repair both sides of my cowl area I let it sit 19 years now I'm fixing alot of rust the raised side I had to fab. My own
Ooof thats work too
@@HOUSEOFDULA yess I had to cut both of the plates off on top to get to it all but I'm glad I did find it all but I been doing autobody n paint since 89 so it was cake walk
Hey I'm having problem with my 1986 convertible the blower motor is blowing but no air is coming out do you know how to fix that

What stereo do you have installed?
In the 79? Its factory Ford AM/FM Stereo
👍🏽
Mike Great vid! On my 87notch i had to replace the fan speed switch, it melted! Got a new one at AUTOZONE😎👍👍Lov the 79!
Appreciate it Mike. Yeah that speed switch it also super easy to replace. Never had one melt! Most likely someone had a fuse larger than factory, the impeller hung up and melted that bad boy lol
How come people in the south always says rats? Rats are big and from the city, mice fit in small places and store shit in cars.
Man I dont know. Rodents, mice, rats. But your right its all mice not rats lol We say a lot of weird stuff like a "coke" = all soda. We dont say "soda pop", ever.
Paint it white again
Plan thus far, wife hates white so trying to get her to see the benefits of keeping original color
Well good luck hopefully she will agree with the white, engine runs cooler with lighter exterior colors
