...I'm just looking for one little bit of help. I emailed IceMark last week, but never heard back.

Basically, the wiring harness from which you do all the testing, which is it?

The closest thing I could find was a large harness which was somewhat attached to the dash, underneath, near the steering column.

I was unable to get it undone, so I just wanted to verify that that is the correct harness before I go nuts and hurt myself trying to seperate the two.

Thanks for any help. I want to get this done tonight, as my Logicon (rebuilt) will be in either tonight or tomorrow. I have the rest of the instructions on testing, it's just unclear exactly which harness is the one I need to get at. Thanks.

emailed you earlier today on it, but here it is again:

So, there are three plugs at the Logicon. Two that plug directly into the back, and the third plug that runs off into the dash and plugs in above the air mix motor in the dash.

We are going to test a couple wires at that third harness.

So unplug that third harness. You now have a car side and a Logicon side. We are going to be testing on the car side of the plug, not the Logicon side.

We need to find the Green w/White stripe wire and the solid Yellow wire in that plug.

Putting your multi-meter on the wires, check for resistance (ohm). Resistance should be between 17 and 21 ohms at 70 degrees F.

If that checks out fine, then jumper 12 volts onto the Yellow wire, and ground onto the Green/white. The motor should move all the way over to the hot position.

If you reverse the two, (12volts on the Grn/wht and ground on the yellow) the motor should move all the way over to the cold position.

You only want to put the 12Volts on the wire until the motor gets to the hot or cold side. Remove the 12 volts after its there.

ok, thanks. Just got that email, too

I'll go do that now, at least, the ohm part. Which wires in the harness are 12V+? Could I just take a hookup wire and jump it that way? I would think that would work... That harness way up in the top of the dash isn't exactly easy to get to, either...this should be fun!

Thanks again

meh, well, was unable to test, so I just put the new Logicon in. Low and behold, everything works wonderfully! Thanks again
