T.P.

OK, I'll dig into that area and take a look. Thanks for the advice!

I don't know if any of the fuses in the fuse box in the engine compartment have anything to do with the lighter but have you checked them?

Your SC doesn't have a second lighter in the rear seat area you could check for functionality, does it?

I once had an air pump mess up a lighter socket. Pump must have been drawing too much current and overheated the lighter socket ... surprised that the fuse didn't blow and protect it. My "new" (at least newer) air pump runs a lot better and apparently draws less power.

I guess you could remove the lighter assembly and take a look.

If your accessory circuit is good maybe you could wire your sat radio to the kick panel fuse box with a piggyback / add-a-circuit fuse holder -- they come in several configurations but some don't allow fuse box covers to close. There's a photo in this thread: http://us.lexusownersclub.com/forums/index...mp;hl=piggyback

If go with an add-a-circuit fuse, using a cheap DC extension cord from a discount store will keep you from chopping up the power cord of your sat radio -- better to cut off the plug from a cheap extension cord.

Thanks for the feedback... I'll remove the lighter assy and look, hopefully that is my problem, but I didn't think about the piggyback idea... I'll try that 2nd..

Hey folks,

electrical mystery here. My cig. lighter in my '94 SC400 went down the other day, was running an air pump off it for sev. minutes, and it suddenly stopped. Fuze checks good (in the driver side kick panel), so I'm at a loss.

Any suggestions on where to look next? Is there another cig. fuze that I don't know about? My satellite radio isn't NEAR as fun without power...

They want to replace the EGR valves? Is your car choking/shaking? Kind of unusual.

ANy chance the car is turning off and on?

Thanks for the reply, no choking/shaking, just the untimely shutdowns. Took it to a competent mechanic, who examined the EGR valve, and says the diagnostics he ran on the valve showed it was OK, so he's going to clean it up a bit. Then he looks at my car (with its 185K on it) and says "have you ever replaced the cables/rotor & caps? It all looks like original equipment, and by the way, it wears out!" So, he'll do a complete tune-up, and then resume...

(yes i have searched the threads and found nothing) It all started when I was driving the car home from work one day going about 80mph with the traffice, then all of the sudden the car just shuts down.

THIS was a timely post...! Because the same thing just happened to me yesterday. Several times, with symptoms just like this post, and finally resulting in the car being in the shop. I have a '94 SC400 with 185K on it.

Of note, my caution lites have been "throwing" an EGR valve problem for 4 months now, and I've run the car with no performance problems or MPG problems. However, the wrench-turners want to replace the EGR valve at a hefty price.

The symptoms make me think it's a fuel problem, and I confess it's been over 100K since the filter MAY have been changed. I'm going to suggest that to the garage as the first thing to do.

EGR valve... anyone with experience with this, and with it's problems?
