Daughters 2016 SF Sport, sporadic unrelated check engine light, only during rain, took to Chevy dealer she purchased from. They charged her $160 to read code then told her they didn't have special Hyundai tools to further diagnose, erased code, car ran fine. 1 week later she got in, while it was raining, NO wipers! She took it back, I called n told them I didn't believe in coincidences and they needed to fix whatever they broke on wipers. They checked and insisted the motor was bad, wanted $500 to replace but they had to order part. I bought a new motor for $110, replaced, still nothing, old motor was good. Checked all fuses, noticed in relay box there was a spot for wiper hi & wiper lo but only had a relay in 1 spot. Put a relay in both, now she has wipers in hi speed only, no lo, no intermittent and wipers don't return to bottom when turned off, you have to turn them off quickly when they are at bottom. Appreciate any help.
