I have a weird problem with the wife's car with intermittent overheat. I took it to my local Holden dealer and they could not find anything wrong; obviously it was not in fail mode at the time. If anyone has suggestions I would appreciate some advice. Here are the symptoms I described to the dealer:
When the aircon is ON, the recycle/recirc light comes ON also, regardless of where the switch setting is; ie the setting is on face or face and floor and the Recycle light is ON.
Attempts to turn the recyle OFF, the light goes off immediately and then comes back ON by itself. Pressing it to OFF again has the same result. After several attempts of this the recycle light Flashed a few times and then went back ON BY ITSELF.
When the aircon is turned off the recycle light also goes out (as normal I expect).
At one stage I could get it to work properly, ie aircon ON with recycle OFF, but then it happened again as per above.
Additionally, the engine temperature is getting too high, ie just under the H, when it normally runs at one notch under half. The engine fan comes on at about the half mark and when the engine is shut down the fan continues to run (as normal). I also heard a click from under the bonnet at some point after the engine was shut down (thermostat?).
I am unsure as to whether the aircon issue is related to the overheating, when I drove the car around my suburb, early on the temp was rising so I turned the aircon OFF and the temp went back down. Later in the trip the temp kept rising even with the aircon OFF. The temp got to one notch below H.
This has come on this week when the wife drove home from work (about 7 klms).
What could cause the recycle to come on by itself?
Does the cooling system, ie getting hot, somehow cause the recycle to come on?
Is the recycle connected somehow to the engine cooling?
Is it a thermostat failure causing the overheating, ie a sticky thermostat? The water level has been checked and is OK.
With summer coming on this could be a problem.
I understand that the dealer tech can only test what is happening when they have the car; if it is not in fail mode then they will not be able to track the problem. After I picked it up from the dealer eysterday I drove it around for 90 minute and all worked fine.
But obviously something is wrong somewhere; I don't know what triggers the fail.
Does the overheat cause the aircon problems or does the aircon problem cause the overheat.
I am tempted to replace the thermostat anyway.
Any advice is welcome and thanks in advance.
Cheers,
Mick
