she is cool, i'm not...
 

E320 wagon, '98, 140k miles. OK, cheap title, but here is the problem. The passenger side (where she sits) AC works fine, but the driver side (where I sit) is not very cold. Cool, but not cold. The blower works fine, it is the temp that is off. Is this the beginning of the end? (not for she and me, but for the old wagon?).

Thanks,

Most likely low on R134a refrigrant...very common.

thanks mbdoc, just to be sure: low refrigerant can cause one side of the system to be cold and the other not?

Best,

I charged the system (turns out it took very little refrigerant, it was within spec already) and the driver's side still does not blow cold. Can someone suggest the next most likely issue and how to address? I suppose I could start by having the climate control head unit tested?

Thanks,
