'99 ML430 - Air Conditioning inop

[milltek]

Hi,

Yesterday while we were on a trip I noticed that the driver-side stop-light wasn't working. Not wanting to drive several hundred miles without it I bought a GE P21W bulb at the gas station and installed it. On the way home I noticed that the a/c was not working. (It was last week.)

When I reached home I checked the underhood fusebox to see if fuse 44 had blown (A/c fans). It was ok. On a short trip this morning none of the instruments and stats lights worked. When I returned from that trip I opened the fusebox to make sure I hadn't disturbed anything, closed it up again and started the car. Now all the instruments and status lights work but the air is still inop.

Anyone care to venture a guess what's going on?

Jim
