The parts in this little kit will do two things. 1. Protect your climate control push button panel. 2. The system will get more accurate readings from the climate control sensor on top of your dash. Many don't realize there is a rotten deteriorated foam hose that has fallen off your center dash temperature sensor thus making the sensor "confused." Many also do not realize an overloaded aux. water pump can damage your climate control panel. Many don't realize the aux. water pump is not even working and can lead to poor heater performance. (It is better to remove it all together than to leave it installed when it won't pump! You will receive a replacement hose and fuse with complete video instructions.
Must do for 1981 to 1985 W123, W126 and R107 with automatic climate control. You won't believe what you find under your dash!!!
