Hello, i just bought this car its a real nice car. The a/c has a small problem. It blows hard all the time firast of all. Second it stays cold for like a minute then starts turning warmer not hot but like cool. Does this sound like freon? also when the ac is on the highest setting the blower motor seems to vibrate. Thank you

Hi pmp,

If the A/C has automatic climate control mode, and is turned to that, it would blow hard at first.

If the blower is vibrating at the highest mode, it could be a faulty blower motor or its blades are out of balance. Could be a missing blade.

When A/c blowers warmer, check the temperature control settings.
Check if the A/C compressor ia engaging.
If it is freon, it would not blow cold at all.
Get the low and high pressure readings so we can understand what could be wrong.

It could be low on freon and the pressure readings would confrim if that is the problem.

If you are not going to get the low and high pressure readings, I would not be able to help you.
