Why Is My Ac In My Car Not Blowing Air. Faulty wiring in car AC system or refrigerant leak can cause no cold. Car air conditioners can break down over time so there are several reasons why your air conditioner isnt blowing cold air.
In most cars the vents can pipe in neutral air heated air or air-conditioned air. Add gas if you need to and make sure that theres a good seal around all of your fuel lines including any metal connections for rubber hoses. It can be changed if not correctly working.
Another common reason for car air conditioner not blowing cold air when idling is an overheated engine.
Generally speaking a lack of refrigerant is the most common cause of your AC system only blowing warm air. Rotated all the unmarked relays around in the junction box. That ice limits the flow of air into your home. But it is not the only cause.
