Hi

Can sombody help me?
The switch for my XJR300 LNA7655BA is impossible to find.
Can the switch for XJC LNA7656AA be used?

 

Freon high pressure 4 wire switch ?

If it is the 2 wire freon pressure switch , it was deleted by a TSB and serves no function on the X300 any longer

2 wire pressure switch only controls the radiator fan motors

Freon leaking or problems with the radiator fans ?

 

Thank you very much!
It is the 2 wire switch, and it is leaking.

 

The TSB in full is to remove the 2 wire pressure switch and replace to a line that has no switch

TSB coming with new blank line part # in the text

 

The text does not have a blanked no switch line part #

With no 2 wire pressure switch in your system it is very important to jumper or splice the 2 wire connector least the fans will blow the fuse and the engine overheats

Initial system design error

Reason for the TSB

I guess that doesn't apply to the XJS? I was not aware that it was deleted from the X300 system...

 

Vee ,

Without me knowing the details of your cooling fans electrical fuse circuit I would assume you come under the same TSB as it behaves the same and the same pitfalls
