98 Caravan Digital Thermometer sender

[speedrcer1]

Hi,

My thermomerter on the overhead console reads OC which means undertemp. After a recent Ice storm it works but reads about 30 degrees low. The sensor must be near the base of the windshield. I smacked the air intake to clear ice)

This is on a '98 grand caravan

Anyone know for sure? And how do you take off the windshild wipers to gain access?

Thanks to all!!

The Temperature sensor is between your grill and radiator.

I am having somewhat the same problem......
I believe there must be a way to calirrate this ....
because I pressed and held both buttons for some time and the letters cal show up .....through messing around with buttons some more I get ...like 10 20 30 ...
Only seem to have 2 buttons to play with ....and I use them like now tomorrow ....and now I think have messed it up even worst......
If someone else does not have the answer ...then I'll mess around a bit more to see if with any luck, I get back to at least where I started....

the numbers that I was speaking of was 1-15 and was for calibrating compass......

dunno what to do for that thermometer...any takers
