I have the same problem on my '86 505 Turbo gas sw N9TE. I haven't
taken a look though I did clean the 3 relays behind the LH head light.
George Nunez had a good explanation of:
http://autos.groups.yahoo.com/group/peugeot-L/message/41843?source=1
The usual summer time cooling probs. Peugeot Pete took the time to write a
good interpretation of a/c pressure readings, here are the switch
functions.
ZDJL 2.2i, N9TXX, ZN3J v6
With manual in hand, the TRINARY SWITCH (an A/C PRESSURE SENSOR) on
the hi
side hose near the drier on the turbo, controls the fans and the
compressor:
TRINARY.... 3 PRESSURE settings that control fans and compressor
1) at below ~22 psi cuts out compressor (not enough Freon)
2) at above ~275 psi put electric fans to hi speed
3) at above ~350 psi cut out compressor
COOLANT TEMP sensor on the front of the thermostat housing
1) at 220F cuts out the a/c
RAD FAN SWITCH on rad by air filter (3 versions: cooler, std, and
hotter ):
1) turn on electric fans on low and engage the clutchable fan at first
temp
of ( 82C=180F cooler) or 88C=190F std)
2) at 92C=198F std. fans go to hi speed ( the first contacts remain
closed)
How do I tell if the relays are good?
Cheers,
