Trip Odometer Won't Zero Out?

Mines getting harder and harder to reset too.
I've asked about it here before. Was told probably "bad capcitors".
I'm pretty sure it's a bad micro switch though, since it shows no other signs of bad Caps and it's a intermittant problem.
You should be able to get a read out without the key in the ignition when you press the reset button, and that don't work either. Which makes me think a bad micro switch.
I'll do the Caps one of these days just to varify it, since it's a cheap fix. Hopefully Digi-key has a compatable switch too, if the Caps don't fix it.

The very first dash cluster i did on a e34 was my own, have since done numerous customers, but one of the symptoms on mine besides the odometer zeroing out on its own sometimes on startup and the gong going off on startup and the gauges acting up, anyway one of the other symptoms that i suspected was a bad microswitch was that i had to push really hard to get it to reset the trip as well and it seemed like it got harder and harder just as you describe. I did the caps and it worked perfect after that.
