Ok so I just went and did the pain in the ***, but seemingly fun chore of removing the dash, removing climate control unit, and replacing the heater core. nothing seems to work. now here is where I seem kinda stupid cause ive never done a job like this, especially with this car, only having it for a couple months...are the hoses that go through the firewall supposed to have anything attatched to them? I cant find a picture or video with it, and I looked like crazy in the FSM. the blower runs, but I don't feel it coming out...its starting to get chilly here and I could also use the defroster!

Nothing works at all? Please be more descriptive.

By hoses, do you mean the vacuum lines? Yes... they go somewhere.
If you have manual climate control, you have 1 hose. If you have auto climate, you have two hoses. They go to the vacuum tank by the engine bay light.

Since you don't have the vacuum lines hooked up, the vents default to floor and defrost. If you don't have any air coming out of those ports, then you didn't properly connect the recirc blower box to the a/c box or heater box.

sorry, I guess I a was vague in my description. the blower seems to come on, (although sounds like an old vacuum) but I don't feel any air coming from anywhere, even floor or defrost. I mean I figured the hoses went to something, wasn't sure if it just funneled heat from the engine to those hoses..I didn't realize they were vacuum hoses cause they were bigger. so do I need to take everything back out and see if the recirc box is disconnected?

Skully

are you talking about these big hoses?

Stowedyco

This is what I got...the auto climate control...2 hoses, are sticking out from the firewall and not going to anything, and it doesn't look like there are any free hoses or anything.[IMG][/IMG]

Those are the coolant lines to the heater core. Someone chopped them and looped them back... so you have no heat (probably because the water valve / **** was leaking). See Skully's pic:

Stowedyco

Awesome! now I have to figure out how to unloop them and hook them back up right?

Skully

Yes, but they were chopped for a reason, so probably an internal leak somewhere like Nismo mentioned.

Stowedyco

where would I start looking? What is the water valve/****?

NismoPick

FSM has all the info.

You can either hook them back up and look for leaks, or take it out of the car and test. It's a pretty safe assumption that there's a leak as it's common practice for the backyard mechanic to just loop back the lines rather than fix the heater leak.

thank you Ill do my research , and see what I can find/fix
