okay gentlemen!!! as you know i have 1985 300d and as usual i drive my benz to work. When i get home or work i leave the a/c switch in the on position and when i get back in the car and turn the engine on the a/c does not come on.

after a few minutes of driving the a/c turns on automatically. i was told by my parts man that the ignition switch is going bad. he said the ignition switch controls the a/c switch and when ever it did not come on, i need to move the ignition switch to the right slightly while the car is running. this should do the trick and kick the a/c on.

i tried that and i had no luck. any suggestions...
