Last night I thought I'd replace the bulbs in my instrument cluster diagnostic information display since it's not been lighting up for a little while now. I took the cluster out and replaced the bulbs and tested it. It worked and so I thought okay now let's put this car back together again. Once I finally did that (hours of work), the display was blank again :tisk:. I just can't catch a break. I always seem to be unsuccessful with fixing things on this car. I have managed to replaced the air filter without any problems :rolleyes:.

I occasionally get one bulb out on the display {one side is bright, the other 1/2 very dim} and just when I think I might actually disassemble dash and replace the bulb, it magically comes on all by itself!!!! It has been doing this on and off for a few years now!!! Cant complain, as both bulbs are original and have over 262,000 miles of use on them!!!!!

the downside is that everything original will begin to fail all around the same time, creating a reason to walk away from the car.....why I kinda think getting rid of it at 300K makes sense.......entire exhaust,alternator,rack,transmission,injectors,most everything is original and waiting to drop dead at any given moment- I would love to walk away from it before it implodes all-together, as so far my ownership experience has been wonderful and trouble-free.I do think that by 1996, they worked out most of the bugs that plagued the earlier models- same with most other designs- they get slightly better each year as they learn the trouble spots.....then they change the model and the process starts over- just look at the 2002Q compared to the 2006Q- many small almost un noticable tweeks along the way

Same thing in my 90Q. I've had new bulbs for 2 years waiting to be installed. Just when I'm ready to break down and remove the cluster both lights will burn bright for a week and I have a change of heart. Getting to the speedo cluster is a PITA so I'm happy to keep putting it off.

Good news! Last night I finally was calm enough to go back and look at the cluster and guess what...it works :woot:. I went for a short drive and turned off the car. Then I started the car again and it was still working. Hopefully, it continues to.
