nm aircon

[roby02]

just upgraded from an NL to a NM
air con switch is doing strange things
turn fan to number one push switch aircon starts (hear compressor kicking in)but no air
turn fan to number 2 and aircon cuts out but fans blow
thought it was switch bought another one and it does same
(could be two faulty switches) but has anyone had this

Go and get an aircon service. Could be any of a number of things.

The fan speeds are controlled through a series of resistors, usually mounted in the duct just downstream from the fan. Sounds like the low speed one has open circuited. You can probably locate it on the underside held in by two screws. Take it to a wrecker or dealer. So long as Ohms & mounting are similiar then any make will do.

thanks
when you say underside is that the underside of the fan housing

Yes. the resistors are in the air stream off the fan to keep them cool. They are like radiator coils.
Of course just to confuse, yours maybe on side or top. But usually in bottom.

so is this the little sucker was screwed up into air duct next to motor

That looks like it. should have 3 to 5 pins depending on number of speeds. Take it to someone capable of checking its ohms
