intermittant aircon

[Deuteronomy]

A few weeks ago i hit a abadger at speed which knocked out my airon and damaged the radiator according to sunwin renault which i had them sort out at great expense. lots of stuff done new readiator aircon regassed leaktested and some switch and undertray replaced

Recently my aircon functions only the first 10 mins or so then cuts out , pressing the button and u cannot hear it it kick in but sometimes it will.

The work they did which i paid for is warranted so i guess ill have to go back to them but is there anyting else it could be that i can get sorted else where as i have had enough of them and its hassle getting the car booked in with them
