A/C not blowing cold

[Nightfox]

Recently I had my Corrado's A/C recharged because it was nearly empty. However, when I turn on the A/C, it doesn't feel cold. The A/C does seem to turn on though - the engine revs up a little bit when I turn on the A/C. What might the problem be?

Ac can be a pita. Fans kicking on at low speed? Compressor clutch cycling quickly or periodically? Test pressure switch?

Maybe you'll get lucky and it'll be the fuse. There might be two fuses, one in the box in the car and one in the engine bay. I believe I recall the one in the engine bay being the culprit for me.

Yeah I'm having a similar problem. Was it the taller fuse in the engine bay that was blown or the shorter one?

Pop the hood and actually verify if compressor is kicking on. If the system was recently charged then compressor had to have been running to recharge.

Did it run cold intially after recharge? If so, may have bad enough leak that system is empty again (low pressure switch will not allow compressor to run to prevent damage).

If AC was not cold after recharge, you could have expansion valve problems (valve at fire wall on passenger side) causing high pressure in system and preventing compressor from not cycling properly.

Could have electrical/fuse isssues as previously mentioned in other replies but had to have occurred after recharging system.

Possibly too much freon in system causing compressor to not cycle on enough.

I took my Corrado into the shop this week to get the A/C issue fixed. They said there was a bad electrical connection at one of the connectors, where some of the wires were loose and not connected. Due to the bad connection, the A/C compressor wasn't coming on. They fixed the wire issue, and now the A/C blows ice cold.

I just got mine back from the shop yesterday for the same issue. One if the AC lines was rubbing against the fan and casued a leak.

Good to hear it was an easy fix for the both of you.
