2001 lincoln continental: left rear suspension is sagging, pumps up when started and starts decreasing when engine is shut off, also all turn and brake light do not opperate all at the same time.
Sounds like the left rear airbag or the air bag solenoid is bad.
Do not see how that would affect tail (turn and brakes) lights also, thinking something electrical, but I checked fuses and relays.
Electrical problem is very likely not related to the suspension problem as you have already figured out.
