Problem With Climate Controll In R34gtt And Odd Switch On My Dash

[urtwhistle]

Hey guys, im having trouble with the climate controll on my r34, even when its turned off and the fan isnt on, there seems to be alot of heat coming through around my feet mainly. Is there a common fault like the heater tap staying open just slightly????

Also if its set to 18' and no AC on it seems to have ambient temp air coming through but if its set on 19 degrees and up it seems to be on full and it defaults to the maximum fan speed. no matter what the ambient temp is the fan speed allways goes to full.

its driving me completely insane, and in summer god knows how hott in the car it will be.

is there any air speeed sensors or temp sensors that are knowen to fall out or fail?????

did i mention its running lpg injection which is great but i dont beleive it is causing the problems because the water in and out for the gas converter is b4 the heater tap............ too my knoledge that is

secondly.

i have a switch to the right of the steering wheel, it has a pic of a big fan and a little fan and you can toggle between the 2. it looks to be an oem, but has no wires going in to the back of it.

try and make it so it is cycling the interior air

u may have it set on outside air coming in which will blow air even if u press the "OFF" button

hey fujiwara,

nah that didnt help. im wondering maybe a temp or fan sensor has crapped it self

[gtst4d]

it could be one of the motors that run of the climate control has craped itself and is stuck in the hot position, my 33 did the same thing and i had to get a new motor to close the hot water tap. Just a though. Try and turn the car on listern for a noise when you change from hot to cold and see if it makes a strange sound or not and see if the heater tap in the engine bay changes position. Best of luck and remember to put up your response when you get it fixed.

Not sure if this will work for you...I had similar issues with mine last year..One day while doing an oil change I noticed just behind the front bar, there was a plug that was unattached, I found where it was supposed to go and plugged it back on...eversince, my climate control has been working fine. Go have a look and see if you can find the plug in the attached pic...if its unplugged, plug it back in...

hey, i'll have a look at that sensor 1st thing in the morning, i was playing with the car tonight.

if i set the climate control to manual all fan speeds work and zones. if i set it for 18 degress ambient air blows out. if i set it for 18.5 upwards red hot air flows out. i tryed listening for the motor or taps. were are they exactly??? are the taps in behind the dash or the engine bay????

As for your second question, my mates 34 had those switched too, and it wasnt wired, he just got rid of them

AFTER 6 WEEKS OF DRVING AROUND WITH THE HEATER ON I FINALY FOUND THE PROBLEM............. just above your left leg is a tiny little vent were the air con sucks a tiny amount of air though. well theres a small temp sensor sposed to be wired in behind it. the wires were hanging off mine. 2 sec job to reattach and the climate control worked perfect again.

yay for me lol
