Hi I recently bought an 85 Sierra badged as the Holden Drover and the wipers are only working at one speed. Is this a relay or a motor problem? And or other? If it is a relay problem does anyone know where the relay is? I’m hoping it isn’t a motor problem as I’ve read it isn’t easy to get to.
I’m starting a rebuild of a Blue SJ51 known in Australia as a Long Wheelbase Sierra. 1.3 carburetor engine (going well) with 4 speed (dreaming of a 5 speed) and working 4WD with manual locking hubs.
All original in rough condition but no bad rust issues, original suspension, panels etc.
