My XJ8 base model 4.0L DOHC is in need to find out what parts I need to take care of following codes. It had been an ongoing thing for about 8 months and this time it has happened within two days. Any help would be greatly appreciated in determining the fix for it.
Code B1858 Climate control pressure switch/circuit failed
Code B1948 Climate control water temperature sensor/ circuit failure
Code B1238 Over Temperature
Is this part of the climate control computer, or part of a fuse block?
Thanks
