Took apart all 4 console switches, dismantled, soaked them all in hot soapy water, then rinsed them before drying them. I carefully put them back together... Lost one TINY bearing on a brick floor in my kitchen!! THat took me 30 minutes to find it! Anyways, after the first one, the rest went easy... overall it probably took me about an hour. I only did one at a time, just in case.
All went well, and the switches and express opening now work beautifully!
Thanks again CJ for the post, though I didn't even look at it... Later I noticed that my switches were, in fact, a bit different... maybe because mine are Express. I appreciate your info.
