First of all there is NO - Olds Delta 98 Regency Elite.

Delta 88 Royale Brougham.
98 Regency Elite
98 Touring Sedan
Seeing you typed in Delta 98 Regency Elite, I will assume you have the
98 Regency Elite. It must be the 98, an 88 didn't have air suspension.
The cylinders in your brake lines are probably something for the ABS.
Maybe somekind of porportioning valve?
Thw switch on the mirror is to turn the Electrochromatic mirror on &
Here is a quote from the 91 Caddy owners manual ----- You automatic
rearview mirror has different positions for light sensitivity. At the -
MAX - setting, bright headlights far away will cause the mirror to
gradually darken. This is a good setting for rural driving. At the - MIN
- setting, bright headlights have to be rather close for the mirror to
darken. This is a good setting for city. When the mirror darkens, it
holds that position until the glare is no longer present.
- OFF - turns the dimming feature off. Some mirrors may read, OFF - HI
or OFF - MIN - MAX .
Transimission ; Changing the oil, & filter is a good start, especially
if the car has sat idle for a year. Might be wise to have the trans
completely flushed out.
Air Suspension : The compressor for the Load Leveling Shocks only
controls the rear of the car, not the front. Check to see you have power
going to the compressor, check the wires, a fuse perhaps?
At 13 years old the car might require a few replacement parts.
Good Luck !
