So I had a new OEM condenser fitted about 6 weeks ago (RAC warranty paid) after air con failed and gas just leaked straight out of the old one.

Picked the car up, all fine, but there was no warm whether for a while, then we had a hot day a few weeks back and no cool air. Was about to return to garage when a few days later, air con started working fine after about 10 mins driving.

This past (very warm) weekend, i did a 400miles round trip - M-way and London driving - aircon perfect all the way. Then today - hottest day of the year - nothing. Hot air only.

Any ideas? TDV8 2007 window tints, Logic 7, side steps.

I would return it for repair under warranty, as if you start "messing" with it could invalidate any warranty.

With regards to ideas, I'll leave that to my better knowledgeable members.  John
