I have a 2005 Elise which is having a problem and with it 95 degrees here I need some help/advise.
Just got back from Car's and Coffee, Jacksonville Fl. , tried to use my A/C for the first time this year (was working fine last summer) and it will not come on, here is what I have done/checked so far. I do have a dealer in Jacksonville but trying to see if there is anything I can do myself before going that route.
On the switch panel:
Fan switch works normal in all speeds.
Temp switch works normal when going from hot to cold.
Position switch works normal when going from floor to vents to defrost etc...
A/C button does nothing and the blue light does not come on.
Recir button does nothing and the blue light does not come on.
Car runs fine, idle does not change when A/C button depressed and I do not hear the compressor engage or anything else happen for that matter.
Car lives in a dehumidifed garage under cover, car has about 9K miles.
What I have checked done:
Main fuse box under passenger side front panel,
Fuse 19 (a/c compresor relay) a twenty amp fuse is good but has no power, engine running / ac fan running.
Engine fuse box next to ecu,
Fuse R8 (recir pump) a five amp fuse is good but has no power, engine running / ac fan running.
Passenger foot well fuse box,
Fuse C4 (ac compressor) a seven one/half amp fuse is good but has no power, engine running / ac fan running.
Switch panel, removed
When I checked all wires connected solid, removed connection to A/C switch and probed all three wires with a grounded test light, no power at any of them, engine running / ac fan running.
Thats it so far, I am at a loss at this point, I did have the a/c system drained and recharged last summer and it ran fine (as fine as a Elise can) and I have done all the listed A/C mods for improvement.
Any help would be apprecieated , if the system leaked down some is there a low pressure switch someplace that interupts power to everything ?
I dont believe this is what happend it seems to be an electrical fault of some kind.
All other electrics work fine,
