Any idea what is wrong with the dash air? I had major issues with mine, I can tell you the roof air is not all that effective where the driver sits,
My problems were ELectrical, OEMTECH linked me to his web page where the answer was.. Well, not exactly found but close enough that I found it based on what he posted there.. It's all good now.. In fact it is 100% now. (He pointed me to the main issue, and I had the cash to fix the "Fix it later" issue as well).
Home is where I park it!
