boy you sure picked a good one i know this sounds bad but its the easiest way i found first remove your hood followed by your passengerside fender to get to all the bolts you need next remove the heaterr hoses

next unbolt the housing and remove the outside half unfortunately you now have to go inside and remove the glove box and the ductwork from the passengerside as well you should be able to see the heater core by now if it still has the factory heater core it will probably be stuck (i used a small pry bar)after alot of twisting and turning it will com out if yours does like mine did but dont worry to much 'cause the new one slipped right in Good luck man and if it not to much trouble roll'em one time for me

Why would the heater blow hot air all the time on my 79 Corvette?

There is a valve which controls the flow of coolant to the heater core, which is a small radiator located inside the passenger compartment. If this valve is open, hot coolant will be pumped into the heater core, which will get hot and warm the air passing over it. If the lever or temperature selector in your vehicle does not control that valve, then the cable is broken, or the electrical control device is not working.

How do you replace a heater core in a 1979 trans am?

You picked an extremely difficult one.......It would be best to get a Chilton's or Haynes for this. I will tell you that it requires pulling the passenger side fender and inner fender well to gain access to it. Some of the later models....such as your '79 have an impression in the fender well that you can cut and bend down to gain access. When done, you bend it back up and seal it.

Why wont the AC fan switch in 79 Firebird work on High how to replace?

your ac fan motor is probably bad (the motor has different speeds, one speed maybe bad), or swicth is bad (alot cheaper to fix) The blower high relay on the top of the evaporator under the hood by the firewall passenger side is not working, may need to replace it.

What could be leaking into passenger floorboard in 79 corvette?

I am not sure, but it sounds like your heater core may be leaking. You may be lucky, and only have a hose leak. But most of the time its the core that goes bad and needs fixed or replaced. You may check under your hood and look at the two hoses that go into the fire wall on the right side of the car. If your lucky one may be leaking at the clamp and only need to replace that clamp. But most of the time it will be the heater core in the fire wall that's the problem and need's replaced or fixed. If you need to drive the car before getting it fixed. You can take both the hose's off the core at the fire wall. And connect them both together with a two or three inch pipe and two clamps. This way you can still drive your car until you get time to have it fixed. Be ware though that by placing both hoses together you will not have a heater. Good Luck M.C.S. The Missouri Crack Shot.......

Where is the blower motor located on a 79 trans am and how do I get to it?

The blower motor on all 70-81 Firebirds and T/As is located behind the passenger side fender. Complete pain to change. The best way is to pull the hood and the passenger side fender and inner fender well. Some people simply cut a hole in the inner fender well to get to the fan and heater core. Suggestion.....if you do either of these procedures, change out the heater core while you are in there. Save you from doing it again when it finally goes.

Will a 350 Chevy motor bolt up too a 1979 Pontiac firebird transmission?

Some Pontiacs came from the factory with Chevy engines. If this is the case on your 79 firebird, then the transmission will bolt up to a 350 Chevy. If the car came with a Pontiac engine, then the bolt pattern is different and would not bolt up.

What car does Jim Rockford use in the Rockford Files I have read that after the first season they used a Pontiac Firebird Formula and would re-dress the exterior to look like an Esprit?

Not that is not true. They used gold Pontiac Firebird Esprits. Started with 76 models then went to 78 models. They never used the 79 model. Three cars were used each season. They all had Firebird Formula engines but were all Esprits.

My 79 firebird wont shift by itself. i checked the fluid while ideling and chased down my vacuum hoses and that's not it either. maybe modulator valve?

I had this problem on a car once. If it won't shift by itself, but it does shift when you go through the gears manually, it's the vacuum modulator. Replace it and you'll be good to go.

What other rear end differentials will fit a 79 firebird?

A complete rear end? If so, any 70-81 Firebird, Trans Am or Camaro. Keep a couple things in mind. ALL Trans Ams were equipped with a positrac....but the Z28 may or may not be. Also, a lot of 79-81 Trans Ams will have disc brake rear ends. You'd need to change your master cylinder and proportioning valve if you don't have a disc brake rear now.
