[W126 Coupe] CIS-E Blues

[Dick Spellman]

A few more questions.  When you say you've tested the EZL.  Did you pull 
the cap and read the resistive values for each of the EZL positions to 
see if it's in spec with the manual?  All of your electrical tests were 
done at the EZL harness so as to affirm the harness is not suspect as 
well as the respective sender or device?
