Try a Couple of Coats of Rainaway or RainX. You will not need to have the wipers on high speed.I've grown accustomed to not having rainsense on the Escalade. That doesn't mean I like it. C'MON GM...OF ALL THE CHEAP LOUSY WAYS TO SAVE A BUCK.
Having said that, my bigger problem now is that, even on HI, the wipers are too slow to keep up with a heavy shower. HI speed on the Escalade is no faster than medium from the days when Cadillacs had delay, lo, medium, and hi. LO speed on my last DTS wasn't much slower than HI on the Escalade. PATHETIC.
Use it, and the RainX washer fluid. Just doesn't seem to last, which is odd as I've used RainX for years and never had any problems. Wouldn't be such a problem now if not for the wipers being so slow.Try a Couple of Coats of Rainaway or RainX. You will not need to have the wipers on high speed.
You can Actually drive in the rain without the wipers, don't recomend doing it but it does work good.
They're great as far as coverage and keeping the windshield clean, even driving at 80mph+, they stay firmly against the windshield. They're just REALLY SSLLOOWW, even on HI. First time I used HI speed, I checked as I thought I'd somehow turned them back to LO as they were that slow.Well my wipers work great, I do keep the blades replaced but I have never had a problem in heavy rain. The wipers will even clean the windshield if it gets to dirty. And when it rains hard they are very fast. This is one item I am glad to have.
