hey got my nubira running bout a week ago but my thermo isnt working fuse is blown on the fuse panel underhood and my fan on the lefthand side looking front on with the engine is really ruff and crunchy fugged i take it... when i get a new fan and fuse if it still dont work where can i look btw my relays tested ok just wanna get some headstarts if it still wont work... and my ac wont fire up

lol put a pin in the valve and there is gas in there mab not enough. is this likely to be costly to fix $99 is standard regas and where would be a good place to look for leakage to save on labour cheers stevie

By "thermo" do you mean heater blower? If so you can't have A/C working since this function is linked to a functional blower. At zero flow the A/C is disconnected.

as in thermo i mean the thermofan on the radiator wich one is A/C and wich one is my cooling fan? i think i know why this is playing up...... but on the A/C subject what do you mean by zero position do you mean the rotation hot and cold switch in the car could i have a malfunction here? the blower seems fine inside the car i have the h and c switch set all the way to cold and the recirc on and fan on not click at the engine or anything i think its out of gas ??

on the A/C subject the zero position was relative to the blower. When there is "no-flow" the A/C is cut. From your description this don't apply in your case.

You may be low on gas. I think I've a similar problem since it's cold here. Even with the A/C green light ON the compressor didn't engage until the engine bay is warmed up. But I still don't know if this is normal as a protection for the A/C system or due to a low gas condition.
Over time I had checked output voltage on the A/C pressure transducer with A/C OFF. You can find results on the picture below. The last one at 0.401V @ -5.5°C was a unfunctional A/C condition. I'll try a coolant kit recharge like the interdynamics.

their is no A/C fan and cooling fan... both fans kick in together and running on low or high speed is decided by the ECU based on the coolant temp

basically both fans will kick in at low speed once A/C is on and coolant temp is under 97C

oh ok so they both should work together at some stage well i hooked the stuffed fans wire into the other fan and swappep the fuses and toyed with a meter all good and its working now so i guess i just have to get another fan and new fuse and it will be sweet...... glad that i dont have to play with the switch thing under the intake manifold is all not in the best spot for hands access now the cars back together..

Both fan turn on as soon as you press the a/c button, at low speed.

as soon as your ECU want to cool down the coolent they switch to high speed, once the coolent has cool down they go back to low speed.(if you still have the a/c on)
