The German automaker, Mercedes-Benz, has long been the producer of luxury, compact convertibles such as the SLK series. Beginning in the mid 90s with the R170, MB has produced this line across three generations. A popular and sporty car, the SLK is not completely worry free when it comes to repairs, as many owners can attest.
One issue that has been reported by owners of the SLK is a problem with the air conditioning unit. There have been instances where the air conditioner will stop working completely and switch itself off. Other instances that have been reported are that the ac unit stops blowing air and will need to be manually switched off and then on again. Even though the fuses seem to be OK, this problem continues to occur much to the frustration of the car's owners.
If the air conditioner compressor is on, that is to say, if you can both hear and feel that it is at least trying to function, then it could be a problem with the blower regulator. If the AC on your SLK is operating in this fashion, or is malfunctioning in any other way, it's time to get it checked out, especially if you live in a warmer part of the country or if summer is coming on.
Take your Mercedes-Benz SLK in for an evaluation by a nearby German import technician. A trained professional can give your convertible and complete inspection to isolate the problem. They will also be able to provide you with an estimate on the cost of repairs.
