Advice needed on strange 360 problem

hmm... you do have the "stop" button out right? The only thing I can think of is to cut the power to the car again, but this time power it back up with the "stop" button out. Perhaps if you turned the power back on with the stop button pushed, the ECU got confused? Just a thought, since sometimes the car seems to have a mind of its own with the windows and such

Is turning that knob off a good idea? I'd just use a battery tender in future to alleviate potential problems like this. Sorry, no idea what this could be other than what was suggested. It'll probably require a SDII hook up if it doesn't fix itself.

 

I cut the power to the car anytime I work on anything major. Never had any major problems. In fact, I think clearing the power has cured a few!

try another reset, you shouldn't have any problems using the cut off switch, we keep them on all our cars in storage, with no problems.
Obvious thing is the "stop" switch on the a/c pannel. But I would evac and recharge the a/c freon, to see if it has got low before getting into too much diagnosis. Had a client last week who had a sudden lack of a/c and wanted elect tests etc, he had all kinds of theroys, because it worked on Friday, but not on Sunday, I was only able to recover 0.4lbs of freon. Put in 1.5lbs system worked fine. Some times when cars sit for a while it "seeps" out a little. If it is low the a/c pressure switch will cut of the compressor.
It may just be a coincedence that it happened when you turned the cut off switch.
Always look for the easiest most basic answer.

 

Outside air temp is probably too low to bring on the A/C.

Why not sit in the car, put your hand on the outside temp sensor under the driver side mirror for 3-5 minutes to get it very warm and then try the A/C again.

I noticed today that I was getting heat like I never did before, and I think that's because the O.S. air temp is low and the sensor is detecting it.

It's worth a try.

 

The A/C connection valves are under the small removable panel, under the hood, on the driver's side, just forward of the bottom of the windscreen.

 

Can we see a picture of your rear grill now after the powder coated ?

 

Looks sharp!! How much did it cost you? Did you take the grill off your self?

 

Hi Mike, when you tried doing the refrigerant charge, did you perform a vacuum to see if you have a leak in the system?

We had a similar issue and found out it was the little valves (where you connect the refrigerant to do the charge) and they were leaking. Try unplugging the caps of these valves, to see if you can here the leak. We ended up replacing the valve stems, and the issue was resolved. This happens when the charge of refrigerant is not done properly.

Hope this works, good luck!

FWIW I had the opposite problem, AC but no heating. The resolution was a new ECU in the AC/Heating of some sort. It was one of those problems where they couldn't really debug it very well when it was hot weather because the heating wouldn't come on normally. I had Ferrari fix it this time last year once it got cold.

 

I'm thinking the problem could relate to the word "Cheapie"
