Nobody knows this information?There are two ice cube relays in front of the fuse box on my 190E '89 2.6. When removed the front one has "A" marked on the base, while the rear one has "C"...
The front one of the relays (marked "A") was the silver 5-pin type but the plug has only 4 slots available. The rear one (marked "C") was the black 4-pin type.
Both are not marked or labeled except for the "A" and "C", can anybody tell me which ones these are?
Requesting pictures, if that is ok with you. So far I haven't found any relay that is located at places mentioned in the posts.The cold upshift delay on my 93 190e 2.6 is on the engine bay firewall directly in front of the steering wheel next to the power brake booster with an electrical connector on the bottom and two vacuum hoses connected to it on the top. I disconnected the electrical conn. and now the trans shifts the same - hot, cold, whatever.
