We always like to talk and blog about upgrading the brakes or suspension or engine. Sometimes however you have to deal with the boring stuff too.
The NA MX-5 electric windows are a resilient but slow design. They raise or lower in geological time scales. If you first pull up at an access controlled gate and then only wind it down to put your arm out, the queue will be hooting and shouting behind you before it’s even halfway.
To make things a bit easier I regularly spray Q-20 (WD-40) down the weatherstrip that also guides the window along the quaterpane. This mostly works but doesn’t last for very long. After 25 years however, the passenger side weather strip decided it'd had enough and tore open around the corner of the quaterpane frame. The result of that was the glass itself pulling the strip out with it every time you wind it up. So I ordered new ones through the local dealer this time. And I have it on good authority that this new pair of weather strips were the last pair at the factory in Horishima.
The removal and fitment is really easy. Both took me about 20 minutes per side. The glass comes with some stoppers which you have to remove while it’s still in the doors; give it the reach-around for that. The weather strips are basically fastened with a bunch of plastic clips, with the exception of one screw each side on top of the quaterpane frame. I really struggled and ultimately failed to get these screws to take thread to tighten it back down again. Their holes are heavily rusted and I probably stripped them on the first try. The clips are destroyed in the process of removal. Fortunately the weather strips came with clips attached, but I had ordered additional ones in any case. When fitting the new strips, I started by feeding the window guide in first for the driver's side, and on the passenger side I first clipped in the main part of the strip and worked around the quaterpane last. There wasn't much difference in the two approaches. Both had the same trouble getting the rubber into place up the quaterpane, and getting the corner seated around the very sharp metal edges at the apex of the quaterpane. I used a credit card and a sharpened toothbrush to help me pry it in without damaging it (never use any metal tools with weather strips and rubber parts in general).
What does a 25 year old Mazda and a new JEEP Renegade or Wrangler have in common? Let’s just say, it’s remarkable how engineering standards and convention has held up over time, cultures and continents.
My handbrake light started staying on. I figured the switch went bad and thought nothing further of it. But then on my way to work in late Feb I hit the brake pedal. Nothing. Straight to the floor. It was the most out of control I have ever felt, and I include the moments like my pirouette, when I ripped the power steering belt trying to powerslide a 96kw car, and my time on the skid-pan at Killarney during an advanced driving course. That day I learnt that if the handbrake light stays on, check your fluid levels!
