S350 W220 - A/C problems, won't blow cold air
hi
, I've tried the reset method on the control climate multiple times but still won't blow cold air.
And it showed 2 diagnostics error codes, one appearing at different times.
First code started in the morning, the error code 1059 comes up:
B1059 Fault in CAN......SAM-FL (Front Left Signal Aquisition Module).
And we played around with the relays trying to figure out the refrigerant relay but to no avail and everything seems fine?
And later at night, the error code 1059 is completely gone even after scanning with the temp controls. But it now shows the 1054 error:
B1054 Fault in CAN......DCM-FR (Door control module front right)
(We did send the car to a mechanic and ran diagnostics, he concluded that the Climate Control is faulty and need replacement, and we bought it on ebay and still waiting for it to arrive. We also sent the original 'faulty' CC to a technician and found no faults whatsoever, which is unfortunate considering we've just bought another CC on ebay.
)
Could someone help me figure out where the problem lies?
THANKS!
p.s.
1. Where can i find the Door control module. Is this really the problem?
2. Is there a way to override or 'trick' the car to blow only cold air. (We live in a hot area, that is ALL we need cold air.)
3. Also, something weird is that the Keyless GO isn't working properly, Keyless Ignition is no longer working, the same time as the A/C stopped blowing cold air.
4. The both left and right lights, wipers are no longer working too
