82 633CSI Barn Find - Newbie Here

[Safari Beige]

Hello boys and girls.. Just purchased a single owner shark with many miles but almost flawless in appearance. Motor has 200K but runs like a champ and no apparent oil leaks. Has a few electrical issues, but I am willing to sacrifice some time to resolve them. Hopefully some quality feedback here will suffice! Build date: 12/81

Nice car! great find. Electrical issues? Please explain. All four power windows do not operate as well as the sunroof. Have not really had the opportunity to start the troubleshoot, but a quick glance at the fuse box indicates the fusing looks proper and no indication of being open. I really do not want to start pulling door panels first, any thoughts?

Not too long ago, I also just bought a 633CSi built the same month as yours. And it's also in incredibly great shape. Regardless, don't trust any of the old fuses and replace them all. Just because they look okay doesn't mean they are.

Check the circuit breaker on the lower panel above the right knee. Also; if anybody has had that lower panel removed: the wires could have been knocked off the back of the switch.

if it is not there the circuit breaker may be under the stereo on the center dash

I don't remember any of the early cars being anywhere other than the under dash panel.

The power window breaker is a great place to start. If it's not that, check the switches internally too. They're prone to oxidizing over the years; not difficult to fix with a steady hand, some contact cleaner and a bit of fine sandpaper. The rear windows are also prone to seizing up, pull the lower panels out to lube the slider post.

The old bullet-type fuse contacts can also "relax" over the years. A quick fix is to use o-rings as springs to increase tension.

Hello Dave, are you saying you can wrap an "O-ring" around the fuse clip to hold the bullet type fuse securely? Could you show me a picture of the quick fix. Sounds like a good idea, I am kind of paranoid to use a needle nose plyer to adjust clips in fear of breaking them. Old fuse box, right!

Looks fantastic, great find.

Second pic should explain all you need to know.

Beautiful find!

If the circuit breaker is popped, it will have a red ring around the base of the push button switch.

There is no red ring around the switch for the early cars.

if you didnt already try it, its worth squirting a bunch of contact cleaner into the switches, the passenger window didnt work at all when i bought my 6 but some contact cleaner into the top of the switch got it working great.

You could also upgrade the switches with lit ones from later models

The car in question is an early model: you can not replace the switches with lit ones from later models.

Early (e12 chassis) cars most times have completely different parts from the later (e28 chassis) cars.

Yeah, careful with that myE28.com link, since this is an E12 car.

Power issue resolved now, was not the 15A breaker, just a switch issue. Operation of windows are sluggish. I used the manual crank, open - close - open -close, feels tight. What type of lube would you recommend for the window guides after I pull the panels?

Thanks for the pic! This is the style breaker installed. The red test button worked as intended. It is located below the dashboard dimmer switch, thank you.

I'd use a nice lithium "white" grease for the motor gear, linkage, pivots & slides inside the door. Avoid lithium grease aerosols, get it in a tube. It's highly compatible with plastics too, but don't use white grease on rubber. Gummi Pflege (http://www.autogeek.net/1z-einszett-rubber-care-stick.html) is nice for that. The rear windows have a single central metal spine that's always caked with old grease.

The switches can be dismantled and cleaned if you're careful. I usually spray them with DeoxIT (http://www.amazon.com/gp/product/B0002BBVN2/ref=pd_lpo_sbs_dp_ss_3?pf_rd_p=1944687582&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0002BBV4G&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1V5AEKSQPPZZ16WBNPNS), then buff the contacts with some very fine wet/dry paper to restore them. Don't go crazy though.

BTW, that Safari is a really nice color on an E24. Great find!
