For about a month, the two lights at the bottom right of our fancy climate control system (by the airconditioning and air recirculation switches) would blink when we first started the car. The owner's manual says this means there's something wrong with the system. Then they stopped. Is this an indication that the problem solved itself or that the system gave up trying to tell us and is now sulking? It seems to work fine - temperatures are consistent with the setting, the fan works, the air conditioning works (we tested it during a hot spell). The Volvo dealer says they'll put it on the computer, but are unwilling to give us a quote just for telling us what's wrong - could be 20 minutes, they say, could be an hour ($104), who knows?

Any advice?
