1990 Mercury Topaz Problems

Drive Train -- Verified

The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the Vehicle Speed Sensor is faulty, however, at times, the driven gear inside the transmission is at fault. Replace the Vehicle Speed sensor and inspect the driven gear upon sensor removal.

Drive Train -- Verified

If the throttle lever is out of adjustment, or the grommets are missing / broken at the throttle or transmission, the automatic transmission can shift hard. Replace the grommets as needed and adjust the throttle lever.

Engine -- Verified

Poor rubber material used in the motor mounts can cause them to fail, leading to a knocking noise or lifting sensation on acceleration. The motor mounts will need to be replaced with revised parts.

Engine -- Verified

Fuel pump failure can cause the engine to crank but fail to start. Diagnosis will show insufficient, or no fuel pressure, and fuel pump in the fuel tank will need to be replaced.

Heating & Air Conditioning -- Verified

Internal heater blower motor issues can cause a ticking noise from the heater blower when the fan is on. To correct this concern, replace the heater blower motor with a revised unit.
