thanks for the help. I'll try and clear the drain see if that alone will help.

hey, I just thought I should mention, I've done a little bit of research since posting and I think it's AC condensation. I tried to find the drain, but I couldn't see it. I have no experience at this so the more detailed the better!

thanks again

Hi, I have a 240 (just base, no GL or anything) made in '92. I get this rattling/grating noise whenever I turn the car with the fan/AC on. It sounds like there's something brushing against the fan, but I have no idea how to check. water also rarely and very small amounts sprays from the fan. lately ...
