The LX comes with a single fixed intermittent wiper speed, around a six second delay. I picked up a wiper control from an EX model that has a variable intermittent control. It directly replaces the LX switch with the same electrical connector but the wipers operate at the same intermittent speed as the LX switch no matter were the variable dial of the LX switch is set. I did this same mod on a '01 Ford Focus without issues and thought it would be a simple upgrade, I could have a bad EX switch but there is probably something different in the wiring between the LX and EX.:crying:
LX Wiper Control Upgrade (NOT)

Years back. This was done on a civic, a fit, and Acura RSX. No issues with it not working. But that was over 5 years ago.
I figured it was a cheap and easy upgrade. It was an eBay find that came off a very low mile 2016 that was in a passenger side collision. For $25 shipped it was worth a shot, switch looked new without a speck of dust or dirt. If some one else does this and it works, I'll assume my used switch was bad and pop for a new one (35256-TV0-A11) which goes for around $60. Or maybe just leave it alone.
Took a look at the 2016 owners manual, (pg.132), it states that on vehicles with the variable wiper control, (EX/EX-L), the wiper speed will increase as vehicle speed increases when in intermittent mode. I guess it is a bit more complicated than I thought. Looks like the ECU controls wiper speed based on vehicle speed, the LX's don't appear to have that ability.
Intermittent upgrade to LX
j2bhrv, you should look at the differences in the wiring diagrams for LX and EX with variable wipers. I upgraded the standard radio on my LX to a factory touch screen unit and found that even though some of the connectors were common, many wires had to be pulled out of connectors and switched around and new wires added for it to be fully functional. Once everything was hooked up properly (pain in the butt), it integrated into the computer fine. At some point I will probably look into the variable wiper issue, but since you are already part of the way there with the switch installed, please let us know.

I've done this mod on my Civic 2016, I had to install a wire from the BCM (Body Control Module) to the wiper switch. I intend to do the same modification on my HR-V LX 2021 also. I'm looking for the wiper schematic.

I've read on some articles you only have to put 1 wire from the stick to the body control module. I have purchased this stick too for the upgrade but i can't find where to put the wire because i couldn't find the HRV wiring diagram
I didn't have time to check if there is a wire on pin 10 of the switch connector. If there is a wire, it should be a matter of relays and fuses.

if there is not, then where exactly the pin position you gonna wire it at BCM?
I removed the connector, there is NO wire on pin 10.
I wonder if the schematics are the same for HR-V and the FIT, because I have all the information for the FIT 2019.
It means the wire would be going from pin 10 (switch connector) to MICU connector B

These schematics are for the FIT 2019, please use as info: The Connector need is B18 (RED) on wiper switch

The way I see it, we need a new wiper switch, a relay (39794-SDA-A03) a fuse (30A) number 5 in engine compartment and a cable from the BCM to the switch. I had a look at the BCM behind the fuse box, it's not easy to get at. I'll give it a try in a few weeks.

Did anyone get this to work?
