Climate Control Not Working
95 SC300 Climate Control does not respond.
No heater, no AC, no Defrost, light, etc. I ohmed out all the fuses on the drivers side kick panel including the CIG Lighter and they are all good. Checked all the fuses on the main fuse box near the battery and all are good. Yes, my Cig lighter works too.
Geez....I'm stumped and not sure what to check next. And the Air Bag light will not go off so I'm not sure if those two are related are I need to reset something.
Is there another place to check for fuses?
Does anyone have a wiring diagrahm of the Control Unit?

I had someone look up the Fuses used for the CC for all those interested. There are 3 places to check fuses.
100a under the hood.
15a Driver's side kick panel. It's the Cig Lighter fuse.
5a behind the CC itself.
I can't find the 5a that is supposed to be behind the CC. Does anyone know where it is?
I took the CC out along with the passenger side lower dash and can't find it. If the 5a fuse is good then, yes the CC has given up the ghost
and it's time to ditch it for a used one.

No. I tore out the lower Dash, glove box, radio, climate control, drivers carpet. I'm stumped.
I need to test the Cig Lighter circuit and follow it to the Climate Control and test the wire at the CC plug for hot there. If it's hot the my CC is bad, if not then maybe there is a 5a fuse inside the CC and I'll tear into it.
Might need one after all.

Can you please elaborate on exactly what you did? Im not totally understanding where you are talking about.
I think this may be my problem as my memory seats arent working either. Did yours start working after you did this ?

If my Cig Lighter is working then I wouldn't see why it would be the Fuse box or a wire coming from there.
I'll check that one out anyway.
Can I back prob the plug going to the climate control? Which wire would be the hot one.? Anyone have a diagram?
