AC Blower
I have a 2008 Isuzu Ascender that it's AC Blower went bad on me and started to smell burnt. I TEST it and sure enough it was no good. I went online to buy it from 1A Auto, the price was excellent and a few days it arrived. I installed and it works just like the factories unit or even better. It's been two years that I have installed the blower and it's working perfectly with no issues. Keep up the good work 1A Auto, consumers you can't go wrong with 1A Auto, their prices and warranty are excellent.
