Re: 1992 toranado tofeo rear
It sounds like there is a problem with the rear air bags. the air bags are there to help give you a softer ride.
3 spots i would check are the air bags themselves, the air pump located under the hood, or a proprtioning valve
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Well you have electronic controlled suspension which uses air shocks among other components. The shocks are unique to Cadillac and your model fits various cars from 1998 until 2005. You can buy replacement parts new, or used. I'm not aware of anyone who makes the shocks in standard form due to the electronic control feature.
Dynaride means that your rear shocks have electronic level control. There is a sensor mounted to the rear suspension. If you add some luggage or persons to the car the rear lowers. The sensor senses this down movement and starts the air compressor which is mounted in under the hood (left fender area). This compressor pumps air into the rear shocks compensating the additional load, so the car remains at proper level all the time. If you start the engine with a delay of about 20 secs the compressor should run for a view seconds to build up the minimal pressure the system needs. If the engine is stopped also with some delay of 30 sec. the release valve opens to vent out all the air.
When this occurs you have an problem with your ride control.You need to replace your front struts on your car.Also it can be that your vehicle may have an problem with your air shocks located in the rear of the vehicle.Sometimes,these vehicles are prone to have an slow leak out of the rear air shocks that as an result cause the service ride control warning to accumulate.
Expensive to fix. There is a lever behind the spare tire which senses load and accordingly turns on the air compressor to pump up the rear shocks. The problem I've had is the one rear shock air line will develop a leak by rubbing against the shock cover which causes the system to continually bleed down. These shocks are about $400.00each to replace new.
sensor could be bad, telling the unit that it was too low so the comp just kept pumping it up??I think there are solenoids at each bag? really cant remember. isnt there a switch in the rear compartment to turn the susp off.
There may be two compressors. One for the air conditioning that runs off a belt bolted onto the engine. No, you don't need it if your windows will go down this summer. As long as it turns, it doesn't have to compress. (You can have other things wrong with air conditioning also). If there's absolutely nothing else being driven by that belt, the belt could even be removed if the compressor is frozen. That would save a little gas if that can be done. There might be another compressor, a little thing mounted on the drivers side inner fender well on some cars. It's for the rear shocks if the car has that kind. If the car still rides and handles ok, you can live without that guy too. Sometimes you replace the shocks with regular ones.
sounds like you need new springs wether it is leaf or coil. . to test a shock push down on corner of veh. and let up if it dosent bounce back to resting with two to three cycles it is most likely worn. you will notice it in the way it handels in the steering when they get bad. hope this helps a little debby
