Toyota Repair: 86 toyota pick up AC, r 134 freon, r 12 freon

Question
Dear Ted,
  My AC is not blowing cool air.  How/where do I change or add Freon?  

Answer
This truck uses R-12 freon which is not available anymore, the solution is to convert the system over to the R-134 freon used by all cars since 1994, the conversion kits are available at most autoparts stores, they come with the valves and the freon and a hose and valve to put the freon in, just follow the instructions that come with the kit. If the kit comes with some O-rings throw them in the trash they are not needed.
