I just replaced the torn Mono Valve on my 1990 420sel. I still have no heat. With the ignition switch OFF when I energize the Back pole (positive) on the top of the mono valve I can hear the valve open and close. I have checked and all of the fuses in the main fuse box all seem to be OK. Am I missing a fuse somewhere. The fan blows just cold air when I turn the control wheel to the red and even to defrost. Would appreciate any suggestions. logs
Still have a w126 cd or library? I have a gorgeous 88 SEC that I have had for 25 years as a daily driver................324,000 miles. I could use some help because nobody in Daytona Beach even knows spark plug torque.......just "tight".
