I recently bought a 91 300E and have some questions:

1. The AC does not work; the condenser needs replacing. Today I noticed that there was HEAT coming from the vent even though the system was set to OFF. There was enough heat coming through the vent that the vent itself was very warm to the touch. Why would that be if the climate control is set to cold? As for the condenser, I saw a Silla for $102.50 on the internet but was quoted a price of $540 for the part from the shop, plus labor of course. Anyone have an opinion on the Silla?

2. The radio has an error message of "WA 1" when turned on - do I just need to re-enter the code?

Thanks all!
