Noise after 140 evaporator fix

[pcalt]

Hello All,
I've recently gone through the evaporator repair on my 1994 S350. Now the air conditioner seems noisier. There are some hisses/gurgling etc coming from the center vents. Has anyone else experienced this? If so, was the repair shop able to solve the noises?

FWIW, this repair has been a nightmare:
1. the shop couldn't diagnose.
2. the job never got assigned to a tech
3. the tech was out sick.
4. they had to replace my ignition
4A. (Forgot about this..) The car overheated 5 miles away due to air in the cooling system...
5. they broke my cruise control arm.
6. the freon all leaked out again - due to some valve leaking
7. they didn't tighten the windshield wiper.

So, confidence is not high that the job was done right.

TIA for any thoughts.
Neil.

Don't take it back to that place again unless you it is a MB dealership. It does sound like a dealership...Am I right? If it is, speak to the service manager and/or the MB service rep for the region. Otherwise, just take it to an independent MB mechanic. May be somebody here can direct you to a good MB mechanic in your area.
It sounds like you have air in your system and the blower fan is out of balance.

J.H.
Unfortunately it is the dealership.

The service manager has been very good with all the problems...

Can you elaborate more on "air in the system" "fan out of balance"... I'd like to use the right words when I talk to him on Friday.

Thanks again,
Neil.

I try to avoid MB dealerships as much as I can. This type of situations are the ones are not, sadly, "unfamiliar" to MB dealerships (with a few exceptions) but you will rarely find in an independent garage. People in this forum have different experiencies and opinions on MB dealerships but, most people would steer you away from them after the warranty is over but, that is another story.
Going back to your problem(s), do a search on the "gurgling noise" on the right upper corner on this screen. I know it was discussed before but, I do not know if it applies to your car. As far as being "noiser": is it the fan noisier, the air, etc? It could be that they cleaned or lubed the blower fan and now it is rotating better. Who knows?
Bottom line is: you paid for it and they have to fix it right.
BTW, how can the service manager been good if you still have the problems and you have no confidence in this shop?? Remember who he works for....

Unfortunately, my regular mechanic couldn't devote the time to do the job, he is just too busy....

I'll do the search on gurgling.... Thanks for the pointer.

Valid point about the service manager. I'll be sure to stress that I want a different tech.

Thanks!
