I am going to try to detail as best as possible what the problem is and what I have done so far in the hopes someone may have an idea what is going on. Essentially I am tying to avoid having to deal with the dealership for downtime reasons and hope this is a simple issue I can fix.
The truck is a 2019 Volvo VNL 760
When using the wipers, all functions work great, intermittent, slow and fast. However when you leave them on for a few hours in slow or fast and then try to use intermittent, the start, stop, start stop, randomly. On the first intermittent pass, the wiper could go up 3/4 of the way and stop for a fraction of a second before going all the way up. It may then stop all the way up for up to 2 minutes, or it may not, on the way down it may randomly stop at random angles before returning to parked. On the second intermittent pass, this issue may not happen as bad, and may randomly stop once or twice. The whole process is random. My wiper switch was replaced for another issue so I know this is not the problem. Other drivers are reporting the same issue to the exact detail. One had his motors looked at and replaced, no change.
Myself, when the wipers act like this I will hear the relays clicking for every time it starts and stops going up or down. So I could hear the relay go nuts if the wipers start/stop multiple times. In the dash fuse, I located relay 23 and 24 which are identical relays marked as INTERMITTENT WIPER. I swapped their positions with each other and the issue went away... for a while until the wipers were used again for an hour.
Need suggestions on what to look at or if this is a case of a useless relay.
I forgot to add, the only other way to get the intermittent setting to work is to shut the truck off completely and let her rest for a day. (Could be less, but I usually have a day)

Very strange engine brake system, If it's Off it still p/ up on low speed, tested on 2 trucks all same. I can't understand VOLVO design this trucks for drivers or for instance companies. Except exterior good look ,everything very cheap and absolutely not reliable. Afraid to take this VNL 760 2019 trucks on the road don't know what I can expect more. First trucks I absolutely didn't trust .Shame on U Volvo

I think all the manufacturers were in such a feverish push last year to get trucks out quality tremendously suffered.
I'd be very hesitant to buy a 2019 made by ANY of the big manufacturers right now.
I bought a 2019 Peterbilt 389L and it was a complete lemon from bumper to bumper. Trully a disgrace on Peterbilts part.
The feverish build Pace has slowed so buying a truck this year should give better quality construction as a 2020 model year.Another Canadian driver and Socal Xpress Thank this. -
