Jaguar xk8 air con light flashes then turns off but air con is on

I'm having a similar issue to the one described in this post:

However, I can not find an inertia switch. I have a 1998 Jaguar XK8 convertible. Does being a convertible make a difference in this switch's location?
I removed the passenger kick panel and also checked in the fuse box door on the dash at the passenger side. Thank you.

Security is set. Could be one problem. Fuel system can do this, but rarely. Takes a scanner to see where to look first.

Brake pedal return spring may be weak or brake light switch above pedal may need adjustment.

I'm not 100% sure on Jags, but on a domestic vehicle you have to clear the code with a scan tool. You should be able to call any Jaguar service center and get a quick answer.

check the PNRD safe switch located on transmission

I ended up taking the car to a dealer for repair.

could just be a vacuum leak or the throttle plates are dirty

sounds like a bad battery connection... ck cables at battery...

go to autozone have them scan it and then clear it record the trouble code and then clear it another option is disconnect the battery both positive and negative and make a jumper wire between the 2 terminals make sure that you disconect the battery very importan

your brake switch, the one that activates rear brake lights has probably failed. Press brakes, have someone see if brake lights turn on, if no then it is a brake light switch problem.
