Plymouth Repair Information

We'll help you out with everything you need to know about your Plymouth vehicle.


Door Light Indicator

Door open light indicator turns on and off erratically.

When the indicator isn't illuminated, try opening and closing the doors one by one. If the door still needs an extra push to make the door light indicator go out, then that door's switch needs to be adjusted or replaced.

If the light stays on even if the door is already firmly closed, then the problem is probably with the body control module or BCM. You got a faulty BCM if its clock gets reset every time you turn your vehicle off. Another indication is your CD player going into radio setting when you turn it on. But to be sure, have your trusted mechanic check your vehicle.


Loose windshield gasket that could be pushed back into place.

If your Plymouth's windshield gasket or weatherstripping pops out back again after being pushed back into place, then the best solution would be to replace it. If the part that comes loose spans over a feet long, then you must replace the windshield gasket. This is to prevent leaks and ensure that your windshield won't fall off or rattle as you drive.

If the gasket part that pops out is just a few inches in length, you may use rubber cement to plaster it in place.

Fuel System (with carburetor)

Oxygen sensor and mass air flow (MAF) sensor are in good condition, but power is low. Mileage is extremely low and engine consumes too much fuel.

If the emission is thick, then the problem might be with the carburetor system. The vehicle guzzles too much fuel because the carburetor gets flooded. This excessive fuel supply makes the air-fuel mixture too rich, thereby making it harder for the engine to burn. Some of the fuel isn't getting burned, hence, the unusually thick emissions.

To remedy this, inspect the carburetor's float system and check if the needle valve and seat are properly closing. If not, replace them. Also, make sure that the float drop (float level) is correct.

Check if the fuel pump is still in good condition. You can have your mechanic check if the pump is producing sufficient pressure.

Air Conditioning

Heater cools down even while driving.

This problem may be due to a leak in the cooling system. Check the radiator hoses, water pump, and heater core. If there's a leak in the radiator hoses and water pump, you should find your coolant pooling under your car. For leaks in the heater core, you can check the floor under your dash. If it's soaking wet and smells sweet, it's a coolant leak.

If there's no leak anywhere in the system, then the problem is with your thermostat. It may be set to the wrong maximum temperature, thus it's not allowing the engine to reach a temperature high enough to heat your coolant. Since repairing the thermostat could be quite expensive, so it's best to get a new one.
