i have no heat in my 1994 mercury grand marquis. what could cause the heat to stop working
A bad starter can cause a Mercury Grand Marquis to not start. A bad alternator or a problem with the security system can be the cause for the car not starting.
Blown fuse.
The shocks are there for a reason. Removing them would cause damage.
Perhaps your timing.
If a 1988 Mercury Grand Marquis shifting out of second gear gets choppy after acceleration then the overdrive band may need servicing. An overdrive band that is sticking can also cause this problem.
Many things could cause this. Loss of air pressure, air pump not working, etc.
mass air flow sensor, O2 sensors, bad fuel pump
no oil in the tranny will cause the bands to streatch and will only allow your trany to work in revers
A blown head gasket.
it's your headlight switch
connect a diagnostic scanner and see what fuel percentage is showing.
