Bypass the car and connect directly to the pcm.

Don't know how that would be done, but boss even said PCM is bad. I'm gonna go for another knowing Cruise and A/C both worked in past. I also used my FSM and traced all fuses applicable and everything is fine.

Well,
Now I know it'* not the PCM, or the EPROM. Upon putting the new PCM in with my original EPROM, the car started seemingly well, A/C went to turn on, cooling fans active...A/C goes off and I also notice there'* a CEL again. I'm sure cruise still isn't working so I figured "ok, maybe the EPROM somehow is bad", so Mike, for ***** and giggles I tried your EPROM, car started fine but same effect. At this point, I'm really out of ideas...I don't even know where to look and what to check.
So to sum it up:
Known not working: A/C and cruise control.
Check Engine Light is on.
We're going to try to scan again, I remembered that the MODIS usually asked for a chip to be installed in the cable to scan my car, and last time it didn't for some odd reason. Talked to old boss again and he said come by so I'll do that in a few days if I don't come up with any other ideas.

I'd really like to know what your boss'* definition of dead pcm is.
At this point in time, I can only recommend going to the dealer and putting the $80 some dollars down to have them hookup the Tech 2 to it. I just hope its not some QDM failure code.

That'* built into the PCM. I didn't mean thats what it could be, I was just dreading the possibility that it could be. Until we get the code, I'm afraid there isn't much else we could do.
