Air Con Woes
« on: 03 July 2010, 15:13:27 »
Further to my recent post I've had the system re-gassed and now when auto is selected the engine jumps approx rpm indicating that the compressor is okay. Also when pressed the fans kick in and I'm assuming it's in an effort to call the car.
However it does not blow cold at all. From looking inside the engine compartment I can hear as if the air con is working correctly but again no cold air in car.
I suspect I may have a problem with either the condenser or perhaps even the air con rad.
Would highly welcome any views before I spend further moneys. Rgds Duggs.

I have a similar problem, fans working, pump kicking in and gas in the system but no cold air  :(  the pipe that runs along the passenger side of plenum chamber is also getting warm, it was always icey cold before.

Can't get to the aircon man until Thurday morning, he's busy until then  :(

My air con does work .... of a fashion  :-/ but the pipe and ally expansion chanmber is also red hot. I don't know if it ever did get cold though, I know it did on my Senator though  :-/

It definately used to get icey cold, used to get condensation on it when the engine was running but now gets quite warm. Don't know whats causing it but i'll find out on Thursday   :y

I normally use the local CoolCarAircon man (Nick) in Reading but he's fully booked until Thursday morning.

Mine was working OK up until last weekend, went to use it Saturday dinner time and it would'nt get cold and was blowing warm air with the C/C set at LO, that's when i noticed that the top pipe was getting warm. It shouldn't be doing that  ;D

Like I say, mine's working .... but of a fashion. Despite various regasses, a new compressor, fill valve, a pressure switch - it could also do with a new condensor according to the expert.  ::)
It was struggling yesterday in 35oC  ::) and wasn't blowing as cold as it should.
It's funny how an ambient of 35 makes the engine temp higher too  ;D it was sat around 98 even when moving and maybe just shy of 100 when crawling in traffic. The extra effort of a caravan on the back might have had something to do with that though.  :y  :y  :y

we were on our way back from France  :y

REALLY appreciate your input and thoughts guys...Seems to be exactly the same problem I'm having.. Will continue to monitor with interest.

Tell me.  With the system OFF....when you hit AUTO do your fans shoot on quite strongly along with the REVs picking up but just ambient air flowing out...NOT cold at all.

You mean interior fan?
It will speed up as it's trying to dispribute the cold air it's expecting to come from the evaporator, but as the cold air doesn't come, the fan just keeps running. My fans were on high-ish all day till ambient eventually reduced and the interior reach the selected temp.

Thank heavens...its not just me then.  Ditto except mine never reaches the colder temp as colder air never appears.

Thank you for the advice but it would appear the compressor is ok..certainly kicks in by the looks of things. Just curious as to where the cold air has gone too !

typically cold air blows out off the top vents and warm air blows out of the footwell vents. if you have lukewarm air coming out of the top vents(indicates that the distribution system is operating)coupled with a warm top ac pipe you are either undercharged (ac gaswise or you have a blockage in the ac system.
