Hey y'all,
I have a 2007 Lib GT-B sedan (postface BL) and I've been autocrossing it. The event can involve sitting in a line up for long periods with either the engine on or off after thrashing the car and wanting aircon in the cabin.
For about 12-18 months the dual zone climate control display has been dead. The system seems to work perfectly as I remember how to use it, set the temp with the dial, auto, fan down, mode to change the fans around, off for none etc. I did take it out and can't see anything obviously wrong with it like burnt out wires.
Recently, I'm sharing the car with 2-3 others for events and it's started overheating at the end of the day. The heat is coming from the turbo being put in a start stop state. A 1-2klm drive usually sorts it but I'd like it to be more reliable or have a procedure to keep it cool and not cook a head gasket. The top res cap spilled a very small amount of white after checking later, just 1 dribble by the looks. Nothing else seems to have spilled.
I've been looking in to a manual thermo fans switch so we can keep the fans running and how to do this. I've added a replacement sti pressure cap at the top res just in case the cap was to blame.
So, I changed the oil today and ran it for a bit while torquing the wheel bolts (to get the oil circulating and do a final top up) and I noticed the a/c pulley and fans clicking on and off a lot. About 28c day, just started the car first time for the day. The a/c would be set to max cold/18c and cabin closed.
I'm wondering if there is a common problem with a/c that can mess with the thermo fans and add to my overheating problem? How to diagnose?
Thanks,
Tim
