Windshield Wipers Concern

A few weeks ago I replaced my CPS on the 99 7.3. Today was the first day I drove my truck in the rain. When I turned my wipers on, I noticed that I lost power and my truck started hiccuping. I read on these forums that an aftermarket CPS is most likely the problem, so I am planning on getting a ford CPS this afternoon. My biggest concern is that before I replaced my CPS, my wipers only had 2 speeds. Also, if I pressed the end of the blinker switch to squirt the cleaner the wipers would not turn off until I turned the truck off. I am not sure why this would be happening and I wanted to ask if there is more than just the CPS involved with this.
Thank you

Could be the wiper switch going out or the contacts being worn to cause the wipers strange behavior. Non oem cps and hiccups are pretty common though.

I changed the wiper switch that's why I don't know what to do next and I don't want to buy a new motor if that's not the problem. Any other ideas? Thanks

First thing to do is get an OEM CPS in it. Check your grounds, especially the one on the driver side of the engine bay. Clean and reinstall.

Some reading for you

Like stated above, a non-OEM CPS will have identical issues with wipers as you describe.

About 5 months ago I noticed a slight grinding noise. Had the stereo been on I would not have noticed. Under the cowl the linkage was wearing out repaired, then a few weeks back the "High/Fast" speed was intermittent, since you have already replaced your multi-switch, it's most likely the wiper motor itself. Sorry.
