To get straight to the point, my heater was blowing but not hot air, my rear window wiper was not working, my driver window button worked sporadically, and my driver lock button from the inside didn't work at all. I have a 2012 Jeep Liberty and took it to the dealership on Havana and Alameda. They charged me $150 diagnostics fee and gave me an estimate of $3000 to fix all the above. They told me I needed to replace my radiator, heater core, and do a coolant flush for about $2500. And then they told me there was intense labor in removing the liftgate to replace my rear wiper motor and master door switch (which would fix my door locks and window issue.) Obviously I got the hell out of there. I googled local mechanics and came across Hotchkiss. It took some time to get my car in, but it was definitely worth the wait. They fixed all of the above issues I had for $800 including an oil change. By the way, I didn't need to replace my heater core or radiator. All I needed was a coolant flush. Hotchkiss has a new customer for life!
