Okay guys, I'm having a predicament. My A/C works, but my defroster, and heater no longer works. I've taken what I can apart and can't seem to find out what's wrong. My plan is to remove the heater core, and misc. heater parts.

My plans are going to install a universal heater, such as

Or the Flex-A-Lite Mojave unit.

But has anyone done anything like this before? I know people usually do it backwards (removing A/C leaving heater).

Take a look at the AC Section in the FSM and trouble shoot your problem.

Your heater is alot easier to fix than the AC.

If you know how taking out the Dash can make for an easy AC/Heater repair.

I've poured through the manual already to see if I could find anything. All the cables are working, but water just isn't flowing into the heater core. The hoses at the firewall are there, and I can only see one hose coming out of the firewall on the inside (being block by the vacuum water ****). This heater design is so silly.

I think I may try to convert into a newer water ****. I've read the thread from Captain Obvious, and he used (from what he believes) is a 2000 Acura TL. I wanted to maybe try that first, but the aftermarket heater units are only two hundred bucks.

You can rebuild that water **** from what I believe. If your not getting water then something is blocking it, plain and simple. Me personnaly I just pull the dash can't stand laying on the floor upside down.

I am getting ready to put my 76 back together and need some help on this to. my water **** is in bad shape but i think it works. don't want to spend the money on a new one. is there a better one that i can use?

I was thinking about doing this, but I'm worried that mine maybe bypassed or something like that. Another reason why I was looking into removing my heater
