I had some issues with my sliding door making noise and air flow/water coming in. Also I had that grinding noise coming from my transfer case when engaging 4x4, so I also asked them to look into that. Also was to stupid to operate the wet wiper system and asked them if this was functioning properly. I spare all details, but today after 2 visits and 3 weeks I could pick up the van. Door is fixed under warranty but they also charged me 391$, 1hr hour each on diagnosing the 4x4 and the wet wiper system . I thought I make decent money, but making almost 400$ in maybe 10min to engage 4x4 and try the wet wiper system is making me think if I should switch my career.
