Sorry it took me a while to report back....I had to wash the battery acid out of my eyes. Now you tell me!

(Just kidding). Some of the problem was traced to fuse "C", but most of the problem was traced to relay "A" (power seat relay). After pulling that, The fuse in "C" no longer sparked. One of "C"s functions is "control unit seat adjustment" so that would seem to be the common thread. No spark at battery now. So do I just replace that relay or do we have deeper issues here?

Also found a dead fuse in position "D", (auxiliary fan, at least that's what the inner lid label says. According to Uncle Stu's "Bible", I'm not supposed to have a fuse there till the 93 M.Y.!). Say, wasn't the aux. fan one of the things I was having trouble with? I need to peek in that fuse box more often! Still don't know for sure if that fixed the fan problem though cause it's cold now and the engine hasn't been exceeding about 80C which is too cold to engage the aux. fan. I guess I could turn the air cond. on to engage the aux. fan but I'm afraid to because the car is very low on freon right now. This is not so pressing right now anyway. I'll just keep a close eye on the temp gauge and tend to this issue (if needed) before the weather starts getting warm again.

I need to make this car reliable again. This is supposed to be the wife's car! I gave it to her because up until recently, it was the most reliable car I had ever owned. Now she's eying my latest acquisition: The 95 E420 (Benzer 4) that I haven't even put in my sig yet! We can't have that! "Bolbo 2" was being groomed to be her next car but I haven't had time to finish him.

Please read paragraph two again. Thoughts?
