Hi, please I bought my jaguar less than six months ago, first the back window is broken, two sometimes when I start the car the heat arrow goes straight to hot, but after a while it goes back to cool. Then also when I stop at the light or to get something the car jerks, like you know jerk and then when im driving I dont feel it. Whats the problem?Thanks

This model year V8 had thermostat problems. I recomment replacing that for starters (be sure to remove the bleed cap when refilling coolant but don't crack the housing). There is also a chance the waterpump could have a loose impeller (not as likely but I've seen these with that concern).

The jerking you are refering to is a missfire. Check the plugs but most likely a failed ignition coil.
