A/C help please

[Drooby]

A friend's 1998 E36 has a very strange problem.
His A/c doesnt work most of the time , and he cant do anything about it ,No fan , no cold air , or anything . Every once in a while while driving , it would turn on by itself.He can then adjust everything but it doesnt last long.

where should we start to troubleshoot.
TIA - drooby

Yes, i guess it was Kinda what you said. We're all just putting our 2cents here - what's the big deal if one says it one way and another the same way but differently?

If it's credit you want for being able to pin-point the problem then it's all yours....c'mon we're better then that.
