Where the signal for dual climate control valve came from
car off?, dont you mean the KEY ignition switch is off?
that must kill all power to all things but headlights and memory feed.
so..... its distribution issue for power, not HVAC.... you think?
ok jose, ever heard of the FSM>? factory service manual,
HVAC is all there, all the tests. etc.
or alldata.com. log in and read it.
with the schematic and a voltmeter this is like what 15 min.work?
why?
what country, USA cars are exported, and guess what, have unique features, options and WIRING.
so post the country, be the first ever here to tell this, vital fact./??
shock me.....?
ill log in to alldata. for you, just you today. (random chance)
i open HVAC chapter, and see? (USA cars)
8 pages of schematics just Climate control, option.
first i decode DCCV, to Dual Climate Control Valve)
this valve is controls by the EATC module. page 2
as as such, (all logic modules) it is bad or the inputs to it are bad.
so what are the inputs.? (power and sensors)
Id say its a power issue, due to its hot and must not be so...
the HVAC pages fail to show which pins are power, (blank names on pins) so had to go to power distribution pages, 5 more pages.
just to find this for you, get an alldata.com account and try self.?
horrid drawings, by maker. (a real FSM will be 10x better)
but id bet , you failed to check all features on the car
and failed to see other things stuck on. huh?
the battery fuse box has SSP relays.
one is stuck on, Fused. (fused, means welded contacts)
id bet.
key off, check the output pin on each SSP, relay, one is 12vdc FAILED
or the control line to them failed.
there are 100s of pages of schematics, working blind is near impossible on newer cars. (unlike 1960 cars)
