Guys, its me Dslbnz.

Have a 2001 E320 with window switches that are inoperative. It started as only the right rear, then the front right went out. Now the RF, RR, and LF are all out.

I tried plugging in a unit from a '98 E320 and it acted the same way. So what else could it be? I thought the '98 + window switch assemblies (the horseshoe thing) were interchangeable?

Thanks for your time and patience.
