Ac wont blow cold air, upper central temp control doesnt work. 2005 Bentley Continental GT
lots for reasons, (huge in fact) cold is 10x more complex than hot.
scan the PCM for errors first. DTC errors
check fuses.
Is the AC compressor clutch engaged?
the 2 lines on this compressor one gets super cold as it passed in to the firewall.
hand on, it even see moisture form on it like cold beer bottle does.
if yes this shows up then the problem is in the dash.
dampers doors dead (blend)
recircu mode.
cold set,
the service manual covers all this, DIY folks need that book
some AC (mine does) has HVAC self test in the book.
with flash codes, (damper blind dead?)
RTM read the manual is always best, check for blown fuses.1st.
Bentley Azur 1996 will turn over but won't start seems, like fuel starvation. checked the petrol pump fuse this is ok. Can't heAR pump when putting on the ignition Any Ideas? Is a New Pump a easy fix?
One check you can do is open the fuel cap see if you hear air rushing in when you open it. If so try starting the engine with the fuel filler cap removed if it starts this indicates the filler cap is blocked and either needs cleaning out or replacing. This causes a vacuum in the tank that will starve the engine Also if there is a fuel filter in the system this should be checked/replaced if filter is full of debris then it would be an idea to have the whole fuel system and tank cleaned out. Often with older cars and especially ones that may have been filled from cans in the past if allowed to run too low on fuel will pick up debris from the bottom of the tank.thy these first before outlay on a new pump to test fuel to the engine. Remove or loosen a fuel line from an injector and see if fuel is present when turning the engine. If so then fuel is not the issue. Hope this is useful.
