The ac was still blowing out cold air for a few weeks while I wait for my navigation unit to send back but all the sudden my ac is not working. I checked all the ac fuses and they seem to be OK. Is there anywhere else I should look for this issue? BTW, I'm still waiting for my nav to send back to be since they can't power on the unit (:.
