Strange problems
 

I have a 94 S350 D 101000
I'm having some strange problems. While driving on the highway I hit a very large bump and my cruise stoped working. It wouldn't come back on after that. a few days later it worked but only until I hit a not so large bump. Next my radio stopped working but would come on after driving about and 1/2 hr. It did this several times and then stoped working altogether. Next I locked my car with the powerlock and when I tried to open the green light came on but didn't open the locks. The green and red lights flash when you press the controler. Yesterday I was driving along and hit a bump and the speedo droped to zero for and instant and began working again and the radio came on with the word CODE flashing. I'm kinda thinking something is loose somewhere but don't know where to look. I checked and cleaned all fuses red + green sensor light is a lot brighter but trunk or doors still don't open. I am
going to replace all fuses and see if that helps,the car had the engine wiring harness replaced at 59000.to me it seems like something was shook loose and it reconnects from time to time.

sounds like a ground problem
