The overhead temperature sensor and its operation are critical to the “automatic” features of the climate control system. If you want the heat to hold steady inside the car, the sensor or sensors must be functioning properly.

The first general automatic climate control was introduced in 1977 in the U.S. market. The system was installed on the 1977 to 1980 280SE, 280CE, 300D, 300CD and 300TD, the 1977 to 1980 280SE, 280SEL, 300SD, 450SE, and 450SEL included the 6.9, and the 1977 to 1980 450SL and 450SLC.

The era of performance cabin air filters really began in 1996 with the introduction of the W210 sedan in the U.S. market. By performance,  we mean more than just a simple intake air box filter like you saw on the later model W124.

When replacing the steering lock assembly in your Benz you will need to remove that little black plastic switch on the side of the lock from the old one and put it on the new part. You can not pry it off, squeeze it off or pull it off by hand. 

If both dash lights are not working including the lights in the upper center console the problem is most likely in the dimmer switch located on the back of the instrument cluster. This is also called the potentiometer providing variable resistance in the wiring to the bulbs.

Would you like to watch an inexpensive on demand video that might help you save $1000's? You could spend three or four hours hunting around the internet on different forums and marginal youtube videos and may get the right info - maybe!

If you have an early 300SD and your vacuum pump fails, you could find yourself “up the creek without a paddle.” The actual mechanism of the pump is very robust and it hardly ever fails, but not so with the rubber diaphragms inside the pump.

This becomes something you should inspect on cars with over 80,000 if they have been driven on rough roads, and over 100,000 on airmatic cars that have mostly freeway mileage.

If you are new to older Mercedes diesels and have not worked on them before, this is one of the first things you want to learn. Especially if you ever run out of fuel. Without knowing how to do this you will never get the engine started again!

If your power seat is not working it is hard to determine if it is a switch, a motor under or inside the seat, or a wiring problem. From our experience  xx % of the time the problem is in a worn out or failed electrical seat switch.

This video covers the step-by-step VERY detailed procedure for removing the W201 rear door panel, inspecting and lubrication components inside, and replacing the door panel without damage. This is why it is 30 minutes long! Kent really covers the subject in DETAIL!

Why do these go hand-in-hand? Well if you do not change the cabin air filter(s) it is likely the dust will work its way into the blower motor and cause squeaking and chirping at low fan speeds. If that noise is ignored you will end up replacement the heater blower motor.

Removing the rear axles from the W201 chassis is not a difficult job provided everthing goes well. In fact, the procedure is considerably simplier than removing axles from the older swing arm rear ends of the 1970's and early 1980's.

This videos covers in detail the removal and replacment of the specialty rear shocks on a 2004 E500. Replacing these shocks are slightly different from removing standard shocks due to the extra electrical connection to the computer.

One of the cheapest ways to fix your worn out W140 blower motor is to replace just the motor. You do not have to replace the entire unit. BUT repairing it this way is not as easy as it may appear!

The voltage regulator is a very inexpensive part that usually wears out between 110,000 to 130,000 miles. It is often neglected and Kent believes many alternators have been replaced over the years when all they needed was a $25 to $30 voltage regulator!!!
