My thermometer (outside temp) display stopped working

It worked before the accident and it doesn't work now. Call the adjuster and have the insurance fix it. You already paid the deductible and your rates won't go up any higher so they might as well pay for it.

Yes, insurance is covering it but no-one seems to be able to fix the problem even the dealer where the car was purchased from doesn't know how to fix it. Thanks for your answer, I will just send it back to them and say fix it!

The other deal is to get the estimate. Have them cut you a check for the repair and keep the money. You can live with no outside temperature display. Just roll down the window and stick an arm out.
