Availability: In stock



What is it?

This is the seal for the plastic cover (or lid) which sits above the heater blower motor. It is suitable for all R107 SL’s with or without air conditioning.

It replaces OE part number 1078350023.

Where does it go?

The blower motor sits beneath the plastic blower motor cover (or lid), inside a chamber within the bulkhead, at the back of the engine beneath the windscreen.

There is a rubber seal that mounts to the bulkhead which the blower motor sits on top of. Above the blower motor, the plastic blower motor cover also has its own rubber seal.

This area is a well known weak spot for the R107 SL.

Why do I need it?

The original Mercedes-Benz items from the 1970s and 80s are made from a plastic that turns very brittle. After years of consistent heating and cooling from the engine, the heater blower motor cover and rubber seal begin to fail. Once this has happened, water can get into the chamber and down inside the bulkhead. Not only does this slowly damage the blower motor, but starts to corrode the car from the inside out.

A faulty blower motor could be noisy, erratic, spontaneous or simply not working. Rust within the bulkhead would explain damp carpets and a musty smell in the cabin.

Our redesigned unit is made from a modern plastic that will last substantially longer; our version more hardwearing than the original.

Through rigorous testing, we have proven that these units perform within 3% of the genuine Mercedes-Benz units, making this the popular replacement choice for SL 107 owners.

What are my options?

There are 4 products to think about when addressing this area of the car:

Blower motor

Blower motor seal

Blower motor cover

Blower motor resistor/control unit

We always recommend the complete bundle deal.

What else do I need to know?

The blower motor cover seal is a very small part relative to the damage that a failed seal can eventually cause. Once water has reached the unprotected metal inside the housing where the blower motor lives, there is very little to stop it causing huge amounts of damage to the car from the inside out.

Understanding the condition of this area on your car is vital to the long term enjoyment of your SL.
