The outside temp sensor on a 91 is located in the front plenum where the radiator and A/C coil sit. You can get at it by going under the front bumper and looking in the small space, it is mounted on the pass side of the box. Yours is probably in the same spot. Mine was acting up but I disconnected it and put it back together and it seems to be working now, might just be a dirty connection.
Good luck.

Ok..i have looked under the bumper. On the left side there is a plastic "box" with some holes in the front. Is that the sensor.

Yup, I believe that the connector for it is inside the engine compartment, the wire leads should go through the plenum through a rubber gromet and connect by the horn. You can take the sensor out and check the resistance at different temps to test it, I don't have the resistance values handy, but I think they are in the Chevy service manual.
Good Luck.

I took the sensor out, kleened it and put it back. It was rather dirty. Now it shows the temp in the garage. It did not do so before. Will take a longer testdrive tomorrow but so far so good.
Will let you know the result.

It`act`s like this now.
Wen i start the engine, HVAC off, it shows 10 deg C. Then it takes abaut 15-20 sek before the right temp apears. And then it works OK
