Everything under the hood for the AC is new. I had the AC pumped down and blows cold. The AC guy had to hot wire under the hood to test it since the switch on the dash doesnt work for some reason.

Any place to start?? The fuse seems fine. How can i test without ripping out the dash??

All you can do is follow the wire back...

ICK!

The AC tech should have helped you narrow it down.

Not that lucky. He didnt want to rip the dash out.

If he narrowed it down to the switch then 'that's that'. IF you have another good switch then you could fish the connector out and test it with the good switch to be sure....

here is the thing. none of the ac switches on the dash work. the blower or compressor. what about the vaccuum lines that run under the dash. can that be the cause.

The vacuum lines only control dampers, they don't turn the compressor on or off.

Check your fuses first including the one running from the alternator to the compressor.

Are the control leavers (heat, defrost) moving the cables for the dampers?

cables appear to be ok. i'll check both fuses again and use a voltmeter. thanks for the advice,

If you take a look up at the switch you can see the wiring connector. Take that off and jumper it for the final test. Of course the radio is right in the freakin' way! You can also get at it if you take out the glove box liner.

Has an aftermarket radio been installed? If it has the ground may have been interupted from the switch... Been there and have the tee shirt>>>>>

I was thinking grounding issues too.

do you know where the grounding wire for this comes out of the dash harness?

The switch just supplies power. The clutch gets the ground from the engine. Since the techie hotwired the clutch and it worked then it's just a power supply problem.

Ok. new update. I have cold air flowing out the bottom ducts. YEAH!!!

However, The air is not coming out the dash vents. is that controlled by the levers on the dash or is a vacuum line for one of the flappers disconnected????

I pushed the control flapper under the dash (mid-passenger side). You can hear the diaphragm (driver side) push air.

Does someone have the layout where the vacuum lines connect? thanks.

I know there is a vacuum diagram in the Assembly Manual. I used it to sort mine out when I put the dash together a few months back.

DOnt have one unfortunately. When i push the control flapper under the dash, the air comes out the front vents. what control this flapper?

All valves (except the temp control door) are controlled by vacuum motors. If I remeber right there are two on the heater box and one on the kick panel, oh yea and the one inside the cowl. It should be the motor that is on the back side of the heater box, between the box and the firewall. It should direct the airflow out to the dash vents (center and both eyeballs.)
I'll try to find that diagram of the lines, but it may take me a while.

interesting. what could be causing this not to open correctly??
It turns out i never pulled the 2 vacuum lines thru the fire wall.

I think one go to the heater valve (RED lINE) and the other goes to the carb (YELLOW LINE). could these not being connected cause the issue? thanks!!

This may help;

pixs help some. im just not sure which hose (colored lines on them) go to which diaphragm valve. I think the one to the cowl, kick panel and the driver side i have correct. it is the 2 that go thru the fire wall and the 3rd to the diaphragm valve flapper on the back of the inside air box (very hard to reach when installed) that im not sure which is which.

OK, Try this, the color codes are on this page (left margin.)
And yes you need to at least hook the hose to the carb/manifold. That is where the whole sytem gets its vacuum source from.

Should be connected to the hollow stud at the passenger rear of the carb. If that stud is missing, any manifold vacuum source will suffice.

10-4. i was playing with the port on the top of the intake. now i have cold ac inside thru the dash vents!!! thanks everyone.
