2000 Mercury Grand Marquis ProblemsCoolant Leak and/or Engine Overheating Due to Cracked Intake Manifold
The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.
The car had 64600 miles on it and the headlights started going out while driving, which can be very dangerous. The problem is in the Light Control Module which is an expensive part (around $500 to $600 + labor).
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
2000 Mercury Grand Marquis Questionsno headlights and wont crank, no turn signal (1 answer)
I have no turn signal or headlight so I disconnected the battery and charged it .
put the battery back in and car wont crank, checked and replaced fuses as needed.
It's a manual panel. I have a blower switch that may be the problem I was told. Is the blower switch behind the control panel? I need to get his working because I have to bring clients in my car for work. Any help would be appreciated.
No crank no start just a clicking noise from starter once it starts it's fine till the next day
