vauxhall vectra cdti - blower only works on 4, MUST BE A SIMPLE ONE?? - carnut1980

hi all, my blower on my vectra cdti 15, 55 plate, only works on no. 4 setting, i changed the resistor pack, but still the same, i changed the switch pack but still same. I removed switch and put a 12v feed to each terminal and i got fan working on settings 1, 2 and 3. These 3 terminals also made the green light show on my power probe, meaning earth (obviously) however the 4th termional (red wire) showed nothing, no earth, and powering it made no difference! so i know the motor is fine and the resistor pack is fine, i also hear the telltale click of the relay, but no fan on 1,2 and 3 setting, on neither of the switch packs i use. I even opened up the switch and the terminals/metal lines are fine. Please help!

Check relay k4 in the engine bay fuse box.This is one of the smaller type relays and controls power to the first 3 speeds.High speed 4 uses a by pass relay circuit,so the resistor pack is not used.

hi, there is no k4 fuse on the box in engine bay. they are all 'r's .a white a brown a yelloy, a gap, a brown, yellow and then red, along with large 40 or 60a fuses to one side, and smaller fuses on the other. If there is a relay for the blower, where is it? When i turn the 'power' switch, to any setting (1, 2 3 or 4) i do here a click coming from engine bay

all sorted now, was loose blue relay, was behind glovebox not in engine bay. Thanks man. i also have non working front fogs and reverse lights, bulbs and fuses are good. Do these run off relays too?
