A/C has been charged twice now in the last year, I can see a leak on the condenser toward the top right at a fitting the shop recently removed that bolt (broke it) nd replaced it and the associated O-ring, that lasted a week blowing 48 degrees, now the 'Auto' part of the A/C dial doesn't light up and the system blows hot air at any setting. we will keep the car another 7-10+ years question should I order a new Denso compressor and Denso condenser then have the shop install it along with anything else they feel necessary to update it. or let them piece meal the system repairs on the cheap and risk multiple down times?
