No heat
Not that I need it in the summer, but I currently don't have any heat. The blower motor works, it blows air, but doesn't blow any heat. The AC has been removed (before purchase) and I don't know what else he took out.
Any idea's what to look for? Can I be missing a part, maybe when he took out the AC?

I think the culpret may be a bad logicon. I had that prob every so often but it would work again after I shut the car off for a couple of minutes and started it again

I never get heat. The blowers always work, but never blow out hot air. Is there a heater core on these cars? If so, where would it be located?

Former Moderator. RIP Icemark.
Please use the search function found in the upper right hand corner of the page.
There you would have found the testing for the air mix motor, which the logicon uses to control the hot/cold.
And if you had read the FAQ for FC sticky at the top of the section, you would have found the links to the shop manuals for the FC. Which would have told you that the heater core is behind the dash, and behind the radio on the FC.
See if people are not answering, chances are that they have answered the same questions, so many times before that they don't want to help anymore

My guess, logicon is not moving your air mix motor. put the car in the "on" position and turn everything off, then move the temperature select thing on the logicon, you should hear a motor move. if it doesnt, try getting another logicon.

listen to all the posts so far, good advice...
you haven't changed your rad fluid recently or drained any coolant, have you? could be vapor lock, but unlikely...try the coolant bleeder valve to see if there is any air in the system...
