UGH! What is up with this truck! (wipers)

[HUMTECH]

Im not saying you cant fix it, trouble is im a flat rate tech, if I spend all kinds of time trying to fix it and it doesn't work I don't get paid. If it does work and fails again within 1 year or 20k im expected to fix it for free. If I replace the part and it fails, covered under parts warranty and I get paid to fix it again. Its a sad reality but that's the system. If I don't cover my ass no one will cover it for me. If it was my own truck, damn right id try to fix it first. I gave a customer the option once to do a repair for way cheaper than a replacement part telling him the repair would likely be temporary but would get him by for about 6 months till he could budget for the parts. 8 months later came back whining that it was broken again, told my service manager I lied to him bout the repair I offered and wanted it fixed for free. Guess what, I ended up doing the repair at half the rate it should pay and the shop covered the parts. Never again
