05 Grand Prix Temp Gauge
I have an 05 Pontiac grand prix. Temp
gauge was randomly dropping off to
nothing while driving. Had a new
thermostat about 6 months ago, just
changed temperature coolant sensor.
Works fine for a day or so then
randomly drops off. When it drops off
if I shut the car off then it usually wont
start again for about 20 mins until the
car cools down again. Shop is telling
me I need a new PCM module....any
other suggestions? I was wondering
about changing thermostat again?
Also blower fan suddenly stopped
blowing heat into the car....still makes
heat as the car warms up it's just that I
cant get it to blow into the car. Hubby
works out of town and I am trying to fix
this myself so I dont have a HUGE shop
bill....any help greatly appreciated!
