The A/C just stopped working in my '93 Roadmaster Estate Wagon - 190,000 kilometers (120K miles). I've kept her well maintained and runs like a charm. Dealer told me that there is a leak in the A/C system and recommends that if I want COLD I'll likely have to have a retrofit. Legislation requires that the new refridgerant is necessary - therefore the retrofit. Anyone have experience with this situation? I haven't been given a firm quote but I'm told it's very expensive! Any suggestions? Much appreciated in advance...
