Bizzare one this! When i reach 70 mph, the needle for the temerature goes down to bottom within seconds. The heater still works and i get hot air through. When i drop speed back down under 70, the gage goes back up to normal within a few seconds! Any ideas or heard of this one before???

check for loose connections on the gauge wiring .. sounds like the temp gauge is losing its power signal !!
