When i turn on my air conditioner in my 1999 durango it blows out hot air. can i put in antifreeze myself or do i need to take to the dealership?

Air conditioning calls for freon, you can install freon in your air conditioner, if you know how, or you can go to a auto part store and ask them, and tell them what kind of vehicle that you have, and purchase the freon kit to refill your sytem, you will have to install the freon on the low side of the air compressor fitting. also you stated can i put in antifreeze yourself, yes you can, just pour antifreeze into your radiator or radiator coolant bottle, but antifreeze is not used for air conditioning as refilling the air conditioning system.

Antifreeze is only for the radiator, does not affect the air conditioner, make sure you have the setting on cold, if it is still hot than take it to your local air conditioner re gas station, most auto electricians do it, dealerships usually send them out which you end up paying extra for!!! You just need a re gas in your air conditioner.
