Is there anyone on the forum that has a workshop manual wiring diagram for a UK 300 ZX TT (1991). we cannot get the air-conditioning to switch on. We suspect that there is a broken wire somewhere between the dash console and pump. Thanks in advance for any help 

These are the UK FSM wiring diagrams for the manual A/C system which should be the type fitted to your car.  There are also extensive diagnostics

pages in the FSM. If you need those I can post the US FSM pages which are essentially the same.

So there are. An online UK/Euro spec FSM would be useful.

AndrewG, that's really helpful. I have dowloaded the links and sent them onto the auto electrician. Will let you know how we get on. 

I sent the diagrams over to my car electrician. What he is trying to establish is "the description and operation of the system I need need to know how the system works ie what says yes you can ground the relay for the compressor"

We possibly need sight of the book that these wiring diagrams were taken from?

I should add that my car has the automatic climate control 

These are the UK FSM wiring diagrams for the auto A/C system (marked LHD - there are no RHD diagrams).

The online FSM is the US version but for the purposes of functions and diagnostics should be suitable for your auto electrician

to work with. The link to the HA (Heater and A/C) section is below (I've used the '94 version as it is clearer to read than the '90):

Hello AndrewG,

Thanks you, I have forwarded the 94 version for the Heater and A/C to my electrician and fingers crossed it provides the info he needs. Few photos of my car attached
