Hi guys

My heater doesn’t work, my electric mirrors don’t work and my windows work intermittently on my 88 cab, any ideas?

They're all fed with power by the two unloader relays K5 and K7, which in turn are controlled by the starter motor.
Pull out K5 and K7, and use a piece of wire to link pins 30 and 87 of their sockets. Do the items in question now work?

Blower motor could be seized up?
