Are you having trouble getting the fan to blow, or does it blow cold air? If cold air, be sure to first check the coolant level as this could cause no heat for the cabin, and can also cause expensive damage to your engine.

If the coolant level is good, it can be a number of things:

There is a control valve in the engine compartment that opens and closes to allow hot water to travel through the heater core. Check for proper operation of this valve.

Secondly, on some of the Jaguars, they were filled with a special coolant that is not compatible with off the shelf coolants. If normal coolant was added to the system without a TOTAL flush, then the two coolants would mix and cause a coagulation. This thickening would in turn plug the heater core.

Lastly, on some Jaguars, there is an auxiliary electric water pump in the engine compartment that pumps the water through the heating system. If this pump fails, then you would get a LITTLE heat once in a while, (especially when high revs, or on a warmer day). This pump is fairly expensive, (what isn't on the Jag), but easy to replace.

Good luck, and let us know what it ends up being.

42 miles with a jaguar. First I love Jaguars. Youll get to your home by a tow truck. The car is talking to you say its sick.Here is what will happen, The TRAC, ASC, light is on okay the APP will now go to limp home mode what this mean it will default giving limited operations, youll probable just go 30mph, and that is just it. The transmission does not know what gear or how fast its going so it communicates to the powertrain it tell it I dont know what Im doing so it activates the traction control and say keep me safe the traction control say okay Ill get disable, then the transmission control tell the powertrain I could be burning up or slipping. So The APP(acclerator pedal position ) gets involved and say we will just limp on home.Remeber i love juguars so does tow trucks

I have a 1999 Jaguar XJ8, there is a Check Engine


the gas gauge is not related, that would be a defective gas gauge sending unit in the gas tank, the check engine light indicates that one of around 200 poss faults has occured in the electronic engine controls, you will need to have the OBD 2 engine control system tested for the fualt code that is stored when the light is turned on.

Xj8 instrument lights not on when headlights on


Make sure the dash lights aren't turned down first of all. I know that sounds basic, but I've seen it happen before. Believe the twist is near the knob to adjust the steering wheel which is lower steering column left hand side. Otherwise, I would check fuses to be sure. finally, the last thing I would do it pull the gauge cluster and check connections as well as bulbs.

1998 xj8 heater only works when engine at higher revs


There is an Electic Water Pump for the Heater that is located under the hood near the left fenderwell. If it's not a fuse, then likely, this pump is bad. Mine went bad in my 1999 Jaguar XJR. It runs close to $400 for the pump, so hopefully that's not the problem. Price does not include labor.

Since I'm comfortable with Electronics, I replaced the brushes in my motor and it works fine now. Heat all the time and only cost $1.00 You may be able to find a shop to rebuild the motor for you at a fraction of the cost.

2001 XJ8 Vanden Plas engine light


I've had the same problem on my 2001. It turned out to be the battery. Apparently the voltage had dropped to the point that the computer began to malfunction. I'd first go to a battery shop and have it checked under load before looking for other solutions.
