Intermitent Wipers

[THK]

Have a 2005 X3 3.0, with speed sensitive intermitent wipers.

While traveling down the highway at 60 mph with a light and I mean light drizzle, the wipers are operating at a continous low wiper speed and say if speed increases to lets say 70, the wiper speed increases. I watching Audi's MB's and other BMW's operating normally.

Is there any way of disableing the speed sensitivity sensor and making the system "regular" intermitent wipers or having the wipers reprogramed for a longer delay setting.

The only thing I can do now is manually trip the wipers to do a single wipe.

Thanks in advace for any direction you can give on this issue!
