96 xj6 having a/c problems.... As car starts it has a constant beep and read Er.

Dumb answer, check the fuse or the switch.

need to run a scan on it

TRY THIS LINK.

Check the condition of the air filter.

i need a diagram of a series 11 xj6 jaguar door i.e. the position of the electric window into the door as i cant line the bolts and frame up. need to see a picture of it. thanks

Lock your doors with key and hold until the alarm activates, then unluck car and start

try the ignition module ,its under the coil

No There are not any lights in the interior door handles of the '96 XJ6

The brake light may or may not be connected the the door problem but I would start with checking the ground wires. i have had a problem with the door lock relay and if that is blown the car will not start.
The antenna is just **** , they get dirty and just stop going up and down.

Hi irvj6ohn:
The 1993 and 1994 XJ6 Fuel Pump Relay is located in the trunk of the vehicle on the right hand rear side. It is light blue and black in color.
I hope this helps.
