I have a lot of natural air coming into my 1990 300CE with all comfort buttons in the off position. I have removed the radio for repair and the ashtray. There is air coming in those areas as well as natural air coming in through the vents towards the doors and some coming through the defrost vents.....is there a seal or something that I can replace?

Seems as though it should be tighter as not to let in heated air during the summer and cold air in the winter....

Thanks in advance.

Sorry, messed up the title!!
