My 96 W210 is blowing cold on passenger side but driver side is not.

Does this mean that the AC needs charging or is there other potential problems?

TIA

Probably it is just low on refridgerant.

That means that you A/C system is about a 1/2 lbs low on freon. I have seen this many time. It should hold 2.2lbs and I bet its down to about 1.4 to 1.6 lbs of freon

Your low on charge,

When you add that 8oz of refridgerant, get some pure 134a. It's unlikely that you really need any sort of o-ring conditioner or leak sealant, and those chemicals often do more harm than good.

A reciever/drier is an 80.00 part, to replace probably an hour or two at most, and 250 to evac and recharge. It shouldnt be more than 500.00.. Ask them for a break down of labor and parts.
