Mercedes Benz SLK230 Blower Motor
Identifying the Causes of Some Common Problems with the Mercedes Benz SLK230 Blower Motor
The blower motor is an integral part of the air conditioning system of your Mercedes Benz. Unfortunately, the motor can run into a number of problems that can affect its performance and make it fail. As long as you can diagnose the issues early on and do the appropriate action, you can deal with the problems before they turn into bigger trouble. The following are some common problems you may encounter with your Mercedes Benz SLK 230 blower motor:
Buzzing noise and vibrations on the dashboard
The noise may be caused by dirt and debris that have entered the motor. You will need to take the blower motor out, so you can inspect it and have it cleaned. Sometimes, the blower motor itself may have gone bad. You will need to inspect the unit to check for any malfunctioning components and have the malfunctioning components repaired or replaced. Check the bearings of the motor as well and see if they are still able to move freely. Lubricate the bearings as needed.
If the airflow isn't as strong as what it was, you may have a clog in the air conditioning system. One culprit is a clogged-up cabin air filter. Take the air filter out and inspect it. Check the surface of the filter elements and the inside of the filter's folds to assess the amount of trapped dirt. Replace the filter with a new one if necessary. Dirt and debris may have found their way into the motor itself. This happens if your cabin air filter is damaged and unable to remove dirt from the air intake. Though a very rare occurrence, mice and other small animals may build nests in the blower motor, hampering its performance. This may happen if you leave your car unused for an extended period. In any case, you will have to take out the blower motor, so it can be cleaned.
No air is being blown
If the air conditioning doesn't seem to turn on, the electrical system may be at fault. The very first thing you will need to check is the fuse. Just open up the fuse box, look for the appropriate fuse and replace it if it is burned out. If the fuse is okay, then have a look at the relay next. Try replacing it with a new one and turning on the aircon to see if that'll do the trick. Bad or damaged wiring may also prevent the air conditioning from turning on. You will need to trace the damage wire and have it replaced in this case.
