Just been through the whole heater blower only working on 4 saga. All advice I found was to change heater resistor, but to check blower motor wasn't stiff, check for wet passenger footwell, and check scuttle under bonnet under pollen filter wasn't blocked. Took off motor but felt free, replaced heater resistor but still only working on four. Thought the motor was u/s and I had blown the new resistor pack so changed motor and resistor pack again. Note The new motor was the cheap version from Europarts not a Valeo motor and was a nightmare to fit as didn't line up very well. Still only worked on four. Ordered a new dash heater control unit off eBay and fitted (Real easy job), but still only worked on four. Went back to wiring diagram in Haynes manual and concluded it could only be a wiring fault or a relay (Which I hadn't thought of). With glove box removed was easy to see blue relay on flip side on passenger fuse box panel. Fourteen quid from Vauxhall and success!! Even Vauxhall guy was surprised, as he said it was nearly always the heater resistor pack that causes this issue.
I hope my experience helps others in a cautionary way, as my advice would be to change out the blue relay as a first step or, with car not running but ignition on so all is quiet, put your head under the glovebox and turn heater blower switch from zero, to one, to two, to three, and to four. If you can hear a click as you turn it to each setting the relay is probably OK and you can start looking at heater resistors etc.
Had the same issue (only working on 4), cleaned scuttle, replaced pollen filter (which wasn't seated in clips so not filtering!), replaced resistor unit. Now the fan works on 2 and 4 but not 1 and 3 and i detect a whiff of 'hot electrics'.
Any ideas please?
