W124 A/C recharge
I have a 1991 300e. My air conditioning is not longer cold, so i think it's time to have it refilled.
I've been reading some post and am kinda confused. Does my model still use freon or some kinda substitute? if it does still use freon do i have to bring it to a shop to get it converted to use the new stuff or can i DIY?
Are the any websites that show the diy and what products are needed? if not i can check with my service CD manual. thanks
