I was short on time, so I had a local mechanic replace my leaking radiator in my 1993 SL2. Alas, in all this heat I recently discovered that my air conditioning no longer works, and all I get through the vents is this sickly, slightly urine-like smell. Any idea to what he might have screwed up? I'm going to be doing some work on the car today, so I thought I might give it a try. Thanks in advance for advice.
