A new problem surfaced. When turn on my Jag, the A/C beeps 10 times and shows "Er" in the display. Ran the diagnosis procedure and errors 12, 23, and 24 are showing up. Has anyone else shown these errors and which one should I try to tackle first or is something else making these errors exist? The A/C seems to be working fine.
Thanks.....

 

Resolved the problem and one other.

1. Disconnect the negative battery terminal.

2. Depress the brake for 10 seconds.

3. Reconnect the negative battery terminal.

Result: A/C errors went away and A/C and all functions working perfectly.

Also, a front turn signal bulb was not working. Now it is working.

I guess I put the Gremlins asleep for now.
