Fusebox and Relay Diagram

Postby HBKHHH » Thu May 16, 2019 7:55 am

Hi

Guys I have just bought a 1990 Isuzu Trooper Bighorn 2.8TD Intercooled but only the front passenger (left) window works Right side rear and front have no power and left rear tries to work but doesnt move i was hoping someone might have a copy of the fusebox and relay diagrams so i can check these first before going any further also there are 2 sensors( well i think they are) right in front of the engine next to each other where the big hose from the radiator connects to the engine could anybody tell me exactly what they are as they are rusty so cleary need replacing one has even had its wire fall off

Thanks
Stephen

More than likely it will be the switches very common on the gen 1 bighorns

I use around 800 -1000 paper to clean up window switch contacts and a little meths to wash the paper so I don't drag as much of the cleanings across the contact surface. If the switch shows melting or contact have changed colour through over heating its a wast of time.

Keeping the regulator assembly driving the window free and an easy run unloads the switches and motors heaps.
