W169 A150 Aircon Wiring Diagram

[michael8554]

<div class="bbWrapper">I need the aircon wiring diagram please, to find out why the aircon isn't blowing cold.<br /> I've yet to go underneath to see if the compressor clutch is engaging, but if it doesn't it would be good to know where to check for volts.<br /> I've spent hours on the internet without success.<br /> Thanks<br /> Michael</div>

<div class="bbWrapper">I used to have WIS on my laptop that covered our old W168, but it didn't cover our replacement W169.</div>

<div class="bbWrapper">Well hours of searching have yielded a surprise.<br /> The compressor is a clutchless unit !<br /> Without that nugget I'd have been investigating why the clutch was jammed.<br /> I didn't come across one internet repair video that suggested the Merc has a clutchless compressor.</div>
