If it either works or it doesn't, that points to a loose connection somewhere probably either at the switch or the blower, or a faulty blower switch on the dashboard. If the blower either works or doesn't, with no intermittent speeds, then it'll likely be the resistor pack, there's a thread in the How Do I section which will explain more.Hera said:The heater blower on my 95 620i sometimes works perfectly : usually not
at all. Any ideas?
How do I get to the switch/blower connections?mac600 said:Hi,
just wondering I thought the ballast resistor controlled the fan speeds and you say youve got all fan speeds there.
So would it more likely be a dodgy connection on circuit ? as your fan either works ok or not at all.?
if it was a suspect ballast resistor I would remove it have it tested first as I bet there not cheap even from scrapyard.
Probably best to get your hands on a copy of the Haynes workshop manual for the Rover 600 or Honda Accord. You'll need to rummage around behind the dashboard and glovebox. Not great to do without some idea of how it all comes apart and goes back together without breaking anything.Hera said:How do I get to the switch/blower connections?
