I searched (not very well maybe) and I forgot my dang service manuals at home so please bare with me.

The air/heat on the Z is not functioning. Absolutely nothing. I want to remove the AC anyway, so removing it is not an issue for me. A fan would be nice, but I can't even get that going.
Power to the fan - fan works
Fuse on the fan = good.

I have the auto climate control and I hate it already.

I need some help getting the fan working via the console control or even a switch. If I only have 2 fan speeds (high and off) I'll be a happy camper. From there I'll rig up some sort of rheostat or something so I can be spoiled with a mid and low speed fan... If I can get the fan working then phase 1 of getting this garage queen on the road would be complete...
From there, I'm going to need some help with the heater. Basically on and off max heat is fine with me. Any idea's of what to do would be phenomenal.

Appreciate any help guys.

 

ACC works purely by vacuum signal. Have you verified that the unit is receiving vacuum from the intake manifold / vacuum tank?

The ACC should still work on defrost (default if system fails). Have you tried the slider on defrost?

 

Have not.

I found 3 cut vacuum lines under the dash to where I think they're going to the climate control. Haven't checked for vacuum from them yet as I'm trying to find out where they're going/yet to connect them yet. I'm searching for a diagram of the acc vacuum so I can get everything connected vacuum wise.


Can't say I have tried the slider on defrost.

If all else fails...Hook up a toggle switch directly to your blower fan. That is what I did, it runs full blast. But keeps me warm, when it gets colder. Just hook it up straight to the battery, and to a switch. Until you get it sorted out. It is better than nothing. Hope it helps. Good luck.

 

Time to bring this back from the dead.

I put the Z in storage again so I can mature a bit before I start romping on everything, but I have the car back at home base and I'm ripping everything out. Body/Paint work soon but I want to sort out this interior first.


I have the dash out and found a plethora of cut in half vacuum lines. I hooked them all back up because after I cleaned them a bit I found they were all color coded.

Now my question. ASIDE from converting to the manual system (I have the manual control box thing on standby if it comes down to it) what would you do to fix your HVAC system while the dash was out? There seems to be a lot of connectors everywhere and it's pretty darn interesting. The top slider on the HVAC box moves well, I'm assuming as its getting turned its blocking off and opening the correct flaps for air. The bottom slider moves freely. I think something's disconnected, so I have to go in there and check things out.

Any tips to get this bad boy going again? I'd like to try and retain the auto air as much as possible.

 

I also am interested, while the weather gets colder (and no garage heater), I will be buried in books and manuals this winter, since I have my dash apart anyway.

I also have a manual climate control, but from what I can tell, it does not have the same plugs..

Correct?

Make sure all the foam strips are sealed tightly.

Also, the Auto & Manual climate control units are 100% interchangeable. I went from manual to auto & back to manual. Plug & Play. Of course going from manual to auto you must install the temp sensors.

 

Yea pull the whole unit out. Tear it apart, use open cell foam where the old foam was. Get rid of any rusty flapper - bead blaster and a can of engine enamel. Washed everything with soap and water. Take ALL the vaccum lines and cut 1/4" off each end an plug it back in where it connects. The lines get hard where they connect and don't form a good seal. The only real issue I had was with the rotory vaccum switch. I took it out of another unit and a better heater core and rebuilt the entire system. It's not that bad - I knew nothing about it and managed to rebuilt the whole thing. I tested all the vaccum relays by drawing a vacuum (eg sucking on a tube) and they all tested OK. Checked the valves as well the same way. Once you tear it apart you've got a good idea of how the whole deal works and putting that open cell foam especially between the blower, A/C (or coupler if you don't have an evaporator) and the climate control unit makes a HUGE difference in the blowing power of the whole deal.

Gents,

In order for the blower to function the system needs a vacuum right?

 

.....

 

No dice. I seem to have far more than just cut vacuum lines under the dash.

I think I'm going to need some photographic help. Some pictures of the vacuum tank and pump would be super helpful. I have vacuum line that was plugged that runs from underneath the vacuum tank (no idea where the other end is) and there's a fat line coming from the vacuum pump (it seems) that goes nowhere.

I'm almost done with bodywork and this is all that's stopping me from driving the car at all. I want to retain the auto air, regardless of big of a PITA it is.

 

Did you download the FSM? It has all the vacuum diagrams.

 

I'll be working on my vacuum lines the next couple days. I'll be sure to take pictures. Do you have a turbo or N/A?

 

Yup, even downloaded the auto air supplement.

That helped me connect a lot of the vacuum lines already, it's just that I don't know exactly what was done to the car and I can't know for sure how and where things are set without an actual picture of the area. The car is a mix of about 3 cars put into one and my father can't remember what the hell he did to the car. The car is ridiculously fast for what it is (I drive Evo's all the time so I know what fast means) and I'm just having trouble with finding and replacing all the vacuum lines so I can have blower motor action. Smoke filled cabins aren't fun.

 

No idea how much I'd appreciate it man! It's a turbo engine.

 

I'll do what I can, but I've got a N/A, so things will be a little different.

 

If you have the schematics you don't need the pictures. Follow the lines and make sure they go to where the schematic says it goes.

If you simply want to turn the fan on don't hook up a switch to it unless you have a 30A switch you're running it off. Run it from a relay instead.

It would probably be a good idea to buy a manual climate control system. Bleach had one for sale last year - dunno if he still has it.

 

The thing is, I don't know where some vacuum lines are or where they originate from or even the parts that are in the car now are even supposed to be there. I think I might have to take a picture or two of what I have and maybe you guys can dissect it. I'll have some pictures up tomorrow.

hey the two vacuum lines that run into the engine bay where do they go i ran a t and put them onto a line off the intake and my heat blows but no defrosters at all? some help would be nice i live in buffalo and defrosters are nessicary thanks
