I have a '91 coupe with Selective Ride Control, which doesn't work. The car has only 50K miles but it is a 20 years old suspension. Is it worth the close to $1K for the shocks to make it work again or should I just go with non adjustable shocks?

It may not be a shock problem. It may be one(or more) of the connections on the tops of the shocks is loose, or otherwise damaged. Might be worth having a shop do a scan on the system to determine what the problem is. You may be able to fix it for little of nothing. Never hurts to try.

I had the "Service Ride Control" light come on and a scan of the codes revealed a bad left front shock. My local Stealership wanted nearly $1k to replace the front shocks. Doing a little web-crawling I found two places that were EXTREMELY helpful.
Captain Z CNC, llc (click here to check out their website) rebuilds the FX3 actuators. Their website has a great diagnostic page that walks you through checking out the function of the actuators. VERY EASY! They also recommended a shop that rebuilds the shocks at about half the cost of buying new ones.
DeltaVee Motorsports, LLC (click here to check out their website) rebuilds FX3 shocks. Rob was most helpful in working with me on a short turnaround window (door to door was just 8 days - which included a weekend and 4 of the days were shipping days!). They did excellent work and the rebuilt shocks work perfectly.
Can't say enough good things about both of these outfits and I'd highly recommend you check them out before laying down a boatload of money on new parts.

I have not personally performed the actuator repairs, but recently had the most common "malady" described to me by a guy that IS familiar with the shocks.
There is a pair of tiny nylon gears under the actuator. They break. On power-up, the system excursions each shock from lock to lock. Then sets the shock at the selected knob position. If a set of gears breaks, the power-up test fails, and you get a code.
There is an aftermarket or individual that is producing the gears in brass. Not expensive. Getting the phasing of the gears correct is important, or it will break the shock valve internals on power-up.

I have heard of "repair" kits for the gears....any idea who offers them(the brass gears)?
