1994 Buick LeSabre Question: My Temperature guage on the dashboard do not move , whats the problems.
It could be the temperature gauge sender unit has failed or if it moves but does not approach the middle of the gauge after five minutes of running the thermostat in the cooling system may be "stuck open". - patrick mannion
or the wires going to the sending unit may be disconnected - sts_rider
