weird heater problems VT Commodore

[Darkk_Calais]

a while ago my climate control stopped working so i tested everythin, heater fan itself works fine... Resistors all good... Relays and fuses all good to... But it dosnt work at all when its on nothing on any speeds,
I bridged one of the relays ('blower relay' closest to the steering wheel) and the fan came on so i went and got a new relay... Still didnt work and now if i try to bridge it again the fan dosnt work it was only that one time....

Anyone have any idea whats wrong with it? Ive tried everything...

Any ideas or info would help... Thanks

check voltage on the plug should be 12v give or take alil, fan might be stuck try give it a jump start by moving the blades.
also hit it a lil see if it works if it does then its not good
