I have a 300 SEL. I just had it in the shop to check Freon level in air conditioner. Today I turned the air on while driving and "pop" the air goes off. Now NOTHING is working on the panel! No air, heat defrost, etc. I replaced the 11 fuse. NOTHING. I called the shop they said maybe a "sensor" problem.

Any idea what I am looking at $ and any ideas of anything else it could be. Never had the problem before they "fixed" the air.

It would help to know what year model or chassis series that you are working on.

Have a great day,
