i have 3 junk mbz books, a 126 cd i bought on ebay, and the official
heating and climate control book i just bought on ebay for a whopping
$129!!! have searched mb groups till i am blue in the face and still
can find no reference as to the identity of the relays in this photo!!
somebody please help me.... i hear people talking of location a,b,c
position etc. can't even find that info. this is an 81 sd. hope you can
help me... -gary
ps. i am working on my a/c and trying to figure out why i have no power
to the pressure switch..
The power windows use relays; in my 116 they are behind the panel to the
left of the parking brake - perhaps in your more modern model the PW
relays were placed here - with the other electrical items. My
supposition, NOT first hand knowledge.
This is the abstract from manual (Chassis and Body, page 1502)
1st version (up tp 9/85)
A Headlamp cleaning system
B Aux. fan
C Aux. fan (preresistor) For engine 116, 117
Heater coil choke cover (preresistor) For engine 110.92
D A/C compressor (up to 9/81)
E Power window/seat adjust.
F Power window/seat adjust.
G,H Aux. heater
I ABS or lambda control
J OVP or A/C compressor
K Heated rear window (up to 9/81)
L Int. wiper
M Fuel pump
First row (nearest to fuse) from left (engine) to right (fender):
2nd row: E,F,G,H
3rd row: I,L,J
last row: K,M
Yours are A,B,D,E,F,L and K. However, these relays have nothing to do
with the pressure switch. The A/C relay controls the clutch.
