Having raced in fairly heavy rain last weekend (it happens with some frequency in the Pacific Northwest), I was again struck with just how feckless my wipers are.

They go slowly under the best of circumstances, and all but stop when I'm going faster than 60 or 70 mph. And the blades don't stay against the windshield at speed.

Is there some relatively simple fix for this, or do I need new motors to make them work right?

Do you still have the little factory aero wing on the driver's side wiper?

I'm pretty sure I have one or more wiper motors around, you're welcome to grab one.

Yes, it the driver's side wiper has the aero wing on it. But it tends to lift off the windshield at speed, on the down-stroke.

You remind me there there's a crumpled red car in my driveway, that would be a perfect donor for wiper motors.

But, seriously, is this a motor issue?

It is not uncommon for the linkage to bind up. remember these are "sunny day" cars and the wipers got very little use as a street car. Disassemble the linkage, clean and lube. Will probably fix your problem.

Rain-x worked well for me-
(1) apply
(2) race
(3) repeat

My wipers were used for for a grand total of 3 swipes during the entire weekend.

Actually Mark, that does remind me- my wipers didn't work on the down-sweep either, but I had so much Rain-X on my windscreen (thanks Greg!) that it didn't matter.

Sounds like Rain-X is the key here.

Thanks, guys!

Mark, I was reading a thread on Miata.net a while ago about slow wipers.
Took my spare and opened it up, cleaned all the old grease out and replaced with cv2. doubled the speed. Should go without saying that you should mark the gear position before disassembly.
Cant help with the lifting problem, maybe weak springs.

I use RainX on my street cars and hardly ever use my windshield wipers.
