Okay couple months ago my A/C was working but needed an A/C recharge because its not that cold. Well now the weather is hotter i turned on my A/C and it blows hot air and so i noticed that my A/C fan isn't kicking on either. Anyone have an idea what causes of this? Both rad fan and A/C fan kicks on when engine is hot though so i don't think the A/C fan is broken. Anyone have any input?

A/C clutch kicking on? If you needed a charge a few months ago, your 134a has probably leaked out again. The condenser fan sometimes wont come on without the A/C clutch engaging. -
Pressure in side your a/c system is not high enough to engage the pressure switch, aka you have a leak.wat?Comment

Pressure could be too high. Since the higher temps we are having now. Your high side pressure has gone up if it goes up too high compressor won't engage.
I filled my wifes altima about a month ago because it wasn't cold enough, never checked high side pressure just added then when it got hot the pressure got higher and AC blew hot air.

while your A/C is on look under the hood by the A/C compressor to see if the wheel pulley is spinning if it's not spinning that means the clutch is not engaged. To test it run a power source to the wire and turn on the A/C if it comes on then you know the clutch is good but there's a problem with it engaging on it's own.Comment
