This page is dedicated to 2nd major problem S-class, SL class, E-class, and some C-class Mercedes vehicles from ‘90s suffer from-leaking A/C evaporator.
Many owners of fine Mercedes automobile drive with open windows not because they want to enjoy 100 degree summer air or make other drivers think that they have extremely freezing A/C . Most likely A/C has no refrigerant due to leaking evaporator core. If evaporator has a leak putting freon for A/C to work for few days doesn’t make sense. It’s expensive and in many cases doesn’t last long. I’m here to help. I can replace your leaking evaporator carefully without any damages to wood and hidden clips.
When I bought 1990 300E A/C system had no refrigerant in it. I bought the car the end of winter and drove it for few months until one warm rainy day I got stuck in traffic during heavy rain. My windows fogged up and I had to put on heat to defrost windows. When outside temperature is 90 degrees and one sits in closed car with heater on, well it’s definitely not cool. I was oven-baked Victor at that moment. I charged A/C system and surely it leaked out in the week. I traced gas leak to leaking evaporator. In evaporator drains I found green dye indicating the leak. Not to be stuck with having heat on in summer to defrost my windows I started removing the dashboard to get to evaporator housing. Once housing was removed I also replaced couple of vacuum actuators as some air ducts did not work properly. Replaced evaporator and went to A/C shop to charge the system (R12 gas is not available at auto parts stores) and lived happily through summer.
When I bought 1992 500SEL I had to remove A/C condenser and radiator to perform engine repair. Previous owner replaced A/C compressor and I was anxious to recharge A/C system and get frozen by great A/C performance. I was happy for 2 weeks. One very hot day I noted A/C is not as cold as it was. After inspection and testing same green dye was found under the car indicating leaking evaporator. I thought E-class evaporator replacement was big and time consuming job but S-class evaporator was big and time consuming job in 3rd degree. I then understood why evaporator replacement is so expensive. It took me 4 days to replace my S-class evaporator under blazing summer sun but was well worth it. I had evaporator to cool all the way down to 32F (according to climate control diagnostic readout pressing and holding AUTO button for 5 seconds). Since then I replaced many customers evaporators in my shop and never had single problem.
I heard stories that people paid over $4000 at the dealer to replace leaking evaporator on S-class. Very few general repair shops will agree to do the job as they have very limited experience working on S-class. Many shops don’t want mechanics busy with one car for 3-4 days. I can take car in and replace the unit in one week time for around $2000. Trust me, it is one big and delicate job.
I replaced evaporators on E-class and S-class. I know all clips and techniques how to remove them without breaking. I’m very neat and will not give you the car back with stains on seats and scratches everywhere. Gloves used at all times not to stain any interior trim. Progress is photographed daily and e-mailed to customer. Final video is recorded with system pressures and temperatures and link sent to customer. Care and attention to details are very important to me. Therefore I work on my own cars myself as I want to do it right and do it myself. Same principle is applied to each and every customer car I work on as if it is my own car.
Below are some pictures made for customer to show progress of repair. Many customer bring cars from other states and I update them daily. Feel free to call me to discuss repair detail
