My service engine light light came on and my cruise control stopped working. Which happened first, I don't know. I checked fuses on the right side of the console as well as the ones undder the hood. They are fine. The car runs fine otherwise. What else can I check before handing over my checkbook?

Depending on what type of trailer you have, a blown lightbulb on one marker could kill them all (like the old Christmas light strings). Look at those, and make sure your ground is good.

i was having a similar problem with my 2000 SL. when the taillights would go, so would the cruise control. and through many bulb and fuse replacements, i finally went into a saturn dealership and they did a recall campaign on it. they did their thing and i havnt had any problems since. FREE!

Yup. The throttle body connectors have a history of failing on these cars. Replace the throttle body and the wire connectors that go to it, and you're back in business. Not terribly difficult and you can get the parts from any dealer. Saturn actually has a bulletin out on this problem but they won't cover it unless you're under warranty - no recall for this.

I had the same problem at one time and what the problem was is a short or an exposed wire connected to the starter which causes the voltage to fluctuate which in turn activates a security feature that stops the flow of fuel to the injectors. The car actually senses the possibility of a spark which could possibly ignite the fuel and be a fire hazard. If you turn the ignition on and off repeatedly after a certain amount of time the car will start and run fine. It is a very intermittent problem.
