93 ZJ AC trouble codes

OK, I put the old ATC system into diagnostic mode and here are the following
codes I got.
33 --- circuit open --- Ambient Temp sensor
38 --- circuit open --- Mode Door feedback Circuit
43 --- circuit shorted --- Solar Sensor Input Circuit
52 --- door not responding --- Blend Air Door Actuator Drive Circuit

Now can anyone tell me where to find these items and how to go about trouble
shooting them further? Anyone (Bill??) have some links or info on replacing
them? or know of somewhere (or someone) online that has or can post the
info??

Cheers

Going by memory and a very poorly written service book. :/

Located on the lower radiator support member behind the grill.
Connector might have fallen off or gotten corroded.
I think it was in the center, but when you take the grill off it
is right there.

Under the right side of the HVAC unit

Located on the defogger grill, top of dash, The black bumpy thing.

Pancake looking thing down by the passengers left foot (If I remember
correctly)

This might help. I've got more pages but they arn't ditigal yet
and the scanner is not cooperating with me today. Got another thing
to fix. yay. :/

If you have had the climate control unit out the connector might
have fallen off, or someone caught a foot on the loom.

Also check the #12 and #24 fuses 15A in the passenger side fuse bay.

ATC/HVAC fault codes, not ECM fault codes. Different doodad.

Ok This I found disconnected (assumming this also displays the outside temp.
on the overhead console), it is now connected.

I'll look for it.

Ok I see it...

I'll check it out

I haven't had it out.. But I'll check things behind there. I'll check the
harness first.

Will do.

Thanks Doug

BTW Doug, have you had the opportunity to check the values of the oil level
sensor yet?

I keep on forgetting when I do the oil change.

I do know it's a pressure sensor and current is sent through
it to ground and road salt/grime will cause a low-level
warning. That indicates it could report level information but
I doubt it is used that way, just a threashold circuit.

That's the unit. It feeds both via the data bus.

np

I have the manual ac on mine so taking pictures doesn't help and the
shop manual is not friendly.
