Please Help on my AC Issue..
I am posting this for my dad.. He has a 99 Ml320 with 85,000 miles.. He has owned it since november of 98. Last month the Ac quit working.. We took it to a very good shop in town to get it checked out.. Turns out it was the compressor.. Dad told them to go ahead and change everything out and to replace with factory mercedes parts. So they said to come back in a week and they would do the work..
He took it in there 3 weeks ago and they changed the compressor along with other parts that you would change.. He picked it up ($2200) and it worked great for 2 weeks, then it started blowing hot air.. He took it back in last week and they kept it for a few hours and told him that a fuse blew and that caused the fans not to kick on and the compressor blew all the freon out of the high pressure port. So they put a new fuse in and recharged the ac and charged him another $200.00.
That lasted a whole 2 days until it started blowing hot air again.. He took it back and they kept it overnight and called him last friday and told him the needed a upgraded diagnostic tool and they cant afford a new one and they cant do anything else for him..
So basically he payed 2400.00 and still dont have a working ac..
Is there anything that yal can think of that could be the problem?
He is 83 years old and at his age every dollar matters.. It just pisses me off they treated him like this..




Instead of directing your anger at this forum, you should have had a few words with the mechanic that fleeced your father out of $2,400.
It seems that your fingers are braver than your mouth.
the motor is located under the dash, not an easy place to get to but possible!!
the motor have a little lever that moves the flap from cold air to hot air when you turn the switch from hot to cold, on a failure status or when the motor malfunction, the lever get stack on the "hot" mode and the tunnel for cold air circulate outside the car keeping you with the hot air. please let me know if it helps any so I can assist you with the repair as well

Why are you even back here?
You are a hot headed individual with an apparent inferiority complex who chooses to use foul language to express himself. Go back to Ford forums where you feel so welcomed and leave us "snobs" to ourselves.
Hate to say this but any *** hole can buy any car the problem arises when they have to service/repair it. These forums, I belong to about 7 MB ones are there to help those who choose to repair their own vehicles. Clearly your idea is that we spend 23 hours and 59 minutes a day writing and reading forums just for you. Had I been an administrator I would have banned you for life for your **** poor comments. I suggest that next time your dad has a problem that he take it Mercedes Benz dealer/workshop and pay the $80 or $100 dollars and hour to get it fixed by them.

The OP's problem occurred over a holiday weekend and he didn't get a response in a timely fashion.
With that said, if you read his posts and those of others, you would understand why his attitude is not a lot to be desired. And everything stems from him not having A/C. It's not as if he was stuck on the side of the road.
Why is it that you are so eager, willing and able to help an individual with his attitude and personality? Maybe you should consider forum decorum instead of trying to be the "nice guy".
