GMC Repair: air conditioner /Rear Right back side car, line assembly, side car

Question
The right rear tire blow out (wife driving) and i think they lost all coolant from radiator and airconditioner i looked under and there are two metal lines broke and crimped then a rubber hose with a cooper line spliced in my question is the cooling lines run to the rear and also i hear a wisile noise from the area i am thinking major repair or what thank you for any help in this area Thanks Pat

Answer
well it could be a major repair, depending on where the lines actually broke off at, if they are broken too close to the rubber to metal fittings you may have to replace the entire line assembly for the A/C and heater from the front of the truck all the way to the rear, hard to say without actually seeing it.  IF the lines are to be replaced it will be quite expensive as the body needs to be lifted to access and remove the lines
