I haven't turned on the AC in 2 years
Bought my car about 2 years ago and was told the AC worked but I never turned it on since I got it. I'm selling the car and guys are asking to try the AC.
Since it hasn't been on for this long are there any potential issues with just turning it on, such as leaks or anything else other then it not working?

The most vulnerable seal is the compressor shaft seal. Generally, before a new compressor is installed, the compressor is set upright so that it's resting on the pulley face end of the unit so that the front seal gets lubrication.

So all you need to do is set your car on it's right side for 24 hrs before starting it up.

If that's not practical, just turn it on and give it a go.

It's best to run the A/C every couple of weeks to circulate the oil in refrigerant.

I do this even in winter.

Lots of cars now use A/C when defroster is on.

To ease your mind, just turn it on; should be fine. I live in N. Mi., and never need it, so forget to use it for a few years at a crack. When I remember, it comes on strong. This is my '05 Elise. gib is correct, it's smart to run it on a regular basis, I just not a AC guy, so never got in the habit of using it.

'70s GM cars would blow fuses the first time A/C was used after a winter! Apparently the compressor oil would resist the movement of the compressor/clutch.

I turn on my Esprit's A/C every week...this HAS decreased leakage of the refrigerant.

Just turn it on and hope for the best.

A/C should be run occasionally to avoid the seals drying out.
