1978 Cadillac Fleetwood problems

Common 1978 Cadillac Fleetwood problems

The 1978 Cadillac Fleetwood is a car that has garnered some complaints from its owners, particularly regarding its engine and air conditioning system.

One common problem with the 1978 Cadillac Fleetwood is related to its engine. The car was initially equipped with a 425 cubic inch V8 engine, which provided plenty of performance. However, after 1980, Cadillacs were saddled with anemic engines until the NorthStar, which had some teething pains. This issue could be caused by a faulty torque converter or a problem with the transmission itself.

Another common problem with the 1978 Cadillac Fleetwood is related to its air conditioning system. The blower in the car is known to operate only in defrost mode, which can be a significant inconvenience for drivers. This issue can be caused by a problem with the blower motor, the blower relay, or the wiring between the two. The blower relay, in particular, is known to be a problematic component in the 1978 Fleetwood. The car uses a 5-pin Bosch relay, which is responsible for controlling the blower motor. If this relay fails, it can prevent the blower motor from operating properly, causing the blower to only work in defrost mode.

In addition to these issues, some owners of the 1978 Cadillac Fleetwood have reported problems with the car's electrical system. The car's shop manual identifies a problem with the A/C system as an electrical problem, but does not provide any further details. This issue can be caused by a problem with the wiring, the blower motor, or the relay, and can be difficult to diagnose without further information.

In summary, the 1978 Cadillac Fleetwood is known to have some common problems, particularly with its engine and air conditioning system. The car's 425 V8 engine can experience issues with the transmission, particularly with the torque converter. The car's blower is known to operate only in defrost mode, which can be caused by a problem with the blower motor, the blower relay, or the wiring. Finally, some owners of the 1978 Fleetwood have reported problems with the car's electrical system, which can be difficult to diagnose without further information.
