Hello guys. I have been looking into my non-working A/C on my 89 Celsior (90 LS400) and discovered I have an error code 11 on the Climate control unit.
According to this site http://www.lexls.com/tutorials/air/accodes.html, error 11 means my Room Temperature Circuit is shorted, fried, or otherwise in error.
Where the earth is that sensor, and does anyone know whats likely to be wrong, how much the cost (if available) or some way to fix it on the cheep?
I'm electronically capable, so no issue with getting out the soldering iron and replacing a sensor or whatever on a board, but first I gotta find it and work out thats likely to be wrong.

Thanks guys.
Philip

my best guess is that it would be somewhere inside the cabin near the driver around the steering column or near the driver's kick panel, maybe behind a grill/grating.
a sensor is usually in this general area to compare inside temp with the outside temp for the climate control to adjust automatically.
best of luck mate!

Thanks mate. I'll have a good look this coming weekend. See what I can find. Hopefully I'll recognised it for that it is when (if) I see it.

The sensor is not only one. The A/C system controls the temperature separately for the driver side and the passenger side. In order to perform this and there needs a compensation for the sunlight, there are different sensors. Sorry that I don't remember exactly where those are located but what I can remember are located under the dash near the steering shaft, near the air ducts close to front side pillars for both left and right, under the front wind shield and near the blower motor.

If it's the sensor near the blower motor, above drawing shows it. It can be found at here.
