Update:
I received my refreshed, repaired and rejuvenated switches from @Zs-ondabrain a couple of weeks ago. I've been so busy and my son is gone in the car so much that I haven't had the chance to drive it until tonight. Wow! The switches feel brand new!
I could see that they looked new when they arrived. The first thing I did after the very quick and easy installation was check to see that the high/low switch works and it does, perfectly. So great to get rid of the mickey-mousey toggle switch the previous owner installed when he couldn't fix it. Too bad he didn't know about Dave's service.
Not only did Dave turn around my switches in a couple of days and get them right back in the mail, but he provided a pair of loaner switches so we could keep the car on the road while he worked on ours. I don't think he usually has a spare pair around to do that (so don't assume this is normal), but it was a really great help to us. Thank you, Dave!
I thought the right-side switch stalk was operating pretty well, but I sent it in with the broken (left side) switch since Dave gives a discount for doing both at the same time. I figured it'd be good for my peace of mind. But the headlight on/off twist switch works so well now, I realize it wasn't operating properly before. It's so crisp and new feeling. It ads a great new sensation to the experience of driving our Z.
I can't say enough about this service. Click HERE to see the page on his site for the service. If your switches feel sloppy/tired or don't work, I really recommend you reach out to Dave.
Looking forward to upgrading to his headlight and taillight harnesses - I hear they are fantastic upgrades.
Thank you again, Dave, for the great service!
