Heater/Climate Control temp

Howdy all,

My heater/climate control unit does not seem to function properly. I only get cold air at 18'c or hot air at any tempertaure above 18'c.

I tried the settings with the a/c on and it made little difference (i.e. the air-con worked but still only left me with hot or cold - so settings in between).

I also tried running the diags and everything appeared normal for most of the settings. When I put it to the sensor check, where the number "5" appears, I pressed the window de-fog button (bottom right next to the recirc button), and i got a reading of between 18'c and 21'c for the first setting (which I assume is the inside air temp - seemed about right), and I got -30'c for the second (no idea what this reads).

Anyone got any ideas? It kinda sux only having a hot or a cold setting, because the climate control does not function properly....

type thing...

There's a climate control temp sensor.... It should have an electrical plug and a suction hose connected to it... make sure bith of these are connected.....

Tool the calibration in the climate controll is out or the external temp sensor is faulty. the climate control thinks the out side temp is -30 so it wants 2 blow hot air to warm the car up. try resetting the climate control (same way as rebooting the ecu) i think that should work. if not then need a new external temp sensor.

hope this helps

I've got the same problem..... where would I find the external temp. sensor??? :confused:

I'm guessing it's somewhere at the front of the car since thats where all the damage from 'the accident' happended, and before that it was all working :D

You'll find the external temp-sensor just under the horn.

At the very front of the car (in the middle).

It's black and is about 3-4 cm's long...

Hope that helps. (I had to re-locate mine as I installed an FMIC).

Cheers

The external temp sensor on my r32 was on the frontbar just behind the number plate.

it's a black little like box, with a metal bracket on it, and a bit of wire.

mayb unplug it, clean it out, u may need to replace. Not sure how it works,

i think the sensor is an active sensor, so it might work from a voltage return.

or it might work by resistive.

I know when i diconected mine to see what would hapen it showed -30'C.

So check the wiring on the plug, move it about....

u may need a new sensor, or your wires shaged or mayb where ever it goes into is disconected or shaged.

Good luck.

Madtrang,

I had a look and was able to find the sensor.

I am little curious as to how you disconnect it. Mind you I was using a blue led light in a car park (really hard to see but better then nothing), as I couldnt find a torch.

It had a cable coming out one side with tubing around it, and the otherside had the bracket connected to it.

So if you could give me any help with disconnecting/reconnecting it that would be fantastic!

      R34 Skyline climate control unit transistor

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
