i am getting a malfunction on the check coolant level and check washer fluid level both are full any suggestions 2003 CLK 500

 

The wiring harness that for these two sensors has them in "series" so if one is unplugged, it triggers both. Check the connections. You may need to remove the front fender shroud extension ahead of the front driver's wheel to get to the washer fluid reservoir and its sensor.

 

will try today i will let u no
