What’s the difference between T3 and T4 timeouts I went to a customer‘s house right now and they had everything replaced but the drop,they were getting multiple T3 timeouts within the past 24 hours. I was the third tech to be out there within a month, but I had no access to the ped so they had to reschedule.

So my wiper stopped working and after multiple diagnostics, I found that the relay that’s built into the fuse block is bad and can’t be replaced. Is there anyway that I can go around that and just wire it to a switch and a speed controller or just a switch? I have a company vehicle and this one just sits but my wife needs to use it because her schedule changed and I have to use her Tahoe for the kids and I really don’t feel comfortable with her driving in wet weather without the wipers. I did ceramic coat the windshield and it’s fine for me because I know how to drive with it but she doesn’t like it so any advice would be great thank you
