Outside Temp Monitor

Help again please. My 1986 190E outside temp display is blank.
I know the sensor is behind the front license plate. Is there a way to test the sensor? If so do you know what the reading(s) would be? If the sensor is good, and i need to change the display, How does it come out from the dash? Is it necessary to remove the dash assy? The maintenance cd i have makes no mention of the sensor and how to repair or replace it or the display.
Thanks again

i know that the sensor works with resistance, and that's how you test it, but, i don't have an ammeter, or voltmeter, or whatever you need to do that, so mine's blank too!

Test values
OC Resistance (ohms)
0 9798 +/- 98
20 3747+/-71
40 1598+/-40

Note: degrees C scale.
Sorry, I can't get the formatting to work. To test at 0, 20 and 40 deg C.

Testing
1 Remove cover under instrument panel at the left.
2 Separate 3-pole plug connection of temperature indicator
behind instrument cluster.
3 Move ignition starter or glow starter switch into
position “2”
4 Test for battery voltage with voltmeter at 3-pole
coupling between lines 0.75 brown and 0.75 black/red.
If there is no voltage, repair interruption in line
0.75 black/red to cable connector interior or line
0.75 brown to main ground behind instrument cluster.
With voltage or ground connection indicated, separate
2-pole plug connection of temperature indicator behind
instrument cluster and measure resistance between the
two line plugs brown and green toward temperature
sensor (test values).
In the event of deviationes from nominal value, renew
temperature sensor together with electric line.
5 If electric lines, voltage supply and temperature
sensor are in order, remove instrument cluster and
renew outside temperature indicator.
5 If electric lines, voltage supply and temperature
sensor are in order, remove instrument cluster and
renew outside temperature indicator.

OK, you get to translate from "service manualese" to English!

I seem to recall this subject came up a long time ago and the answer was no it can't be changed.

Avatar says Delaware?? Not a US vehicle? All USA 's should be Fahrenheit. Seems to me, if you want it bad enough it can be done. There are parts cars around or a junk yard and pull all that's needed. Sensor and display unit should do it. Maybe the entire cluster, I don't really know. I would assume they function the same, wiring that is.

Edit: Shinglebacks How To says you can replace the sensor and or the gauge. I would assume now you can replace the gauge into your cluster and most likely order from the dealer.

mmm I just bought some mirrors from Nes and he asked me if mine was working. He's a salesman :-), I bought more than I went for. I believe he just may have one or two laying around. nescid1@verizon.net He also sells on Ebay.
