My spark started making a hissing noise behind the dash board. The noise is there when the a.c. is selected to be on. When the a.c. is not selected the noise is only there when the vent selector switch is set to defrost. While sitting idle with tthe a.c. the noise is there. If you rev the engine the noise goes away for a bit then comes back. Checked the a.c. pressure and it appears to be normal when checked with bottle refill kit.
If you're going to install HID's, please install them properly. The halogen reflectors or not designed to properly disperse the light from an HID bulb. Either use casper shields (which usually come with a good brand HID kit) and aim them properly or do a retrofit of them with the proper projectors. Another option you could do is install a headlight harness with ceramic connectors and run 90w/100w bulbs. Those are pretty bright and less strain on the eyes of oncoming drivers than improperly installed HID's.
I just purchased my 2014. I have a scan Guage II on it. Usually don't 65 it will crop up to 210F them about down to 188/194F and then crop back up again. So the weeks chronic thermostat is not variable. It's either open or closed. I'm new to these electronic thermostats but they seem to work. Ive always felt with the real old school stuff.
