89 525i Blinking DIMS / speedo won't speedo, still (archive)

Thank you all who advised. I am still experiencing problems.

My car is a 1989 5251 with 155,000 pampered miles.

I purchased a new LCM (Global Imports, Atlanta 278.00) and installed. I did this becuase one of the relays was actually bad. Problem is : it still blinks off (dims) randomly. Is it possible a new LCM has bad ground connections? I have checked the various grounds and power drop, everything seems ok. I am reluctant to re-solder the commections on a new unit. I can "rap" the top of the box and the lights will come back on sometimes for a short while sometimes for the duration of my trip. I hate to take this to the dealer, it's probably a simple fix. I will check with the dealer to exchange the unit if they will not I will re-solder.

The other problem is still the speedometer. It takes between 3 and 7 miles for it to start working in the morning (almost like it has to warm up). sometimes it tries to work and drops back to 0. I have checked the connectors and cleaned them externally. I have not cut the seal to actually remove the connecter, that is next.

Surely someone out there has had this problem.

Thanks in advance
