I have a 1990 Sierra 1.8 CVH and the electric cooling fan has stopped working. I fitted a new sender unit in the block but still no joy. I thought maybe a fuse had blown but cannot locate a fuse for the electric fan in the fusebox. Anyone know where it is or what else the problem could be. I had 12 volts across the motor and that is okay.

If I remember rightly, this fuse will be out on its own down by the glovebox, you'll need to take that out and/or the underfelt in the n/s footwell, should be a fuse behind it,strapped up to the loom.

Thanks for reply. By removing the soundproofing in the nearside footwell I can see a 30 amp fuse up behind the glove compartment which is okay and a yellow relay. Is this the right fuse and is the relay to do with the fan ?

I'm not sure about the Sierra's but some vehicles esp Japanese use a sender in the bottom of the radiator to operate the cooling fan. I see you have checked the sender in the block but this maybe for the gauge.

That'll be the fuse, can't remember off-hand about the relay. If you're sure the fuse is live both sides, you'll need a meter to check, but pull the relay out, see which terminals are live, pull the fuse out and if you lose a live, that will be the cooling fan relay.
Have a look in the fusebox for one the same colour (should be the same type relay, maybe h/lamps?) and try substituting.
