Clean and test 850 1993

posted by  someone claiming to be Ronjon on  Wed Sep 3 02:11 CST 2003 [RELATED]

There are 4 temperature sensors in the cabin for ’93 850. Two of them are located, each, near the door jams behind handles, inside roof cloth cover. I took them out and cleaned all dirt off of them with WD-40 and a toothbrush. I have not have the problem since (My fan and climate control used to shut off, specially when using AC). The sensors have fans behind them causing dirt buildup through out the years.

Other two sensors are inside the vent tunnel behind the center dash and they are fairly clean. I pulled them out and put them back with ties, after a major struggle, without taking the whole dash apart. However, I think, the other two were the culprit.

Sensor test: Most of the sensors, especially these, are tested for continuity. Use an ohm or multi-meter to see an 8 - 15 ohms resistance reading (or was it kilo-ohms?? I forgot the exact range).
