I should have mention that the owner was out today and this was done by his assistant.who in the oast had charged me 50 to 100% of what the owned did.
When I picked up the car the AC wasn't working right and when I got it home I realized that the Aux fan was turnig backwards and blowing towards the front of the vehicle. so he obviously didn't test it much

My issue is not with the shop that I recommend to everyone I know but with the helper who I think I should discuss with the owner

obtw the Aux fan came from Mercedes shop and came with only loose pins that needed to be inserted into the old connector. the color code on the new one i sreversed from teh original and if you wired it as teh original was it will turn the wrong way
I fixed this and its running fine
