Even after replacing the switch in my 1996 Buick Roadmaster Estate Limited, I have no delay wipe. Only MIST, LO & HI.

On my 1996 Buick Roadmaster Estate (wagon) Lmiited Collector’s Edition, there must be a control unit somewhere in the vehicle so that I can get my delay wipe interval settings back. Thanks!

If you share what year, model, and trim level you have, it'll be helpful.

I'm not sure if yours has the RainSense sensor. When I bought my '05 LeSabre (yes, it's not a RM or RMW) my delay would not work. The only thing I got was a single wipe when I moved to a new delay setting. Oh, and the headlights turned on after about 15-20 seconds.

I unplugged the sensor and all of my delay settings suddenly started working!

My car does not have rain sensing wipers, thanks for your suggestion.

Dang. I wasn't sure, so it was a shot in the dark. Sorry it didn't help.

That’s OK, thanks for helping anyway.

Thanks, great information. I will run some tests, as I am a mechanic. I just do not know where to look.
