Hello Guru's My First post should have been an introduction about myself and my 1996 C280 being a proud owner, And I am happy with my purchase.

I detailed the whole car including the Engine Compartment because it was Filty but now my A/C seem to work when it wants to. When i Turn it on it blows hot air, sometimes after a few minutes it blows cold air then it gets hot again...

Any Ideas What went wrong? Friend said this cars Engines is ment to be dirty and most C class owner who washes there
engine compartment gets this problem?Is This True
I did the search but no luck

Please Help
Thanks in Advance
