air conditioning problem

[SECURITY]

whenever i turn on my car, i get this kind of buzz then click (bzzz*click*) (hard to explain) kind of noise like somethings trying to turn or twist behind the middle of the dash (i suspect the air con fan) i dont want to rip apart my dash before i know what it is.. so any ideas?

also, when i turn my air con on, i get this kind of vibration from the fan outlet on the left side, whenever i turn up the fan level, it gets louder and the vibration gets heavier..

anyone know what the problem is or/and how i can fix it?

not sure man but could it be the fan belt slipping?

[SECURITY]

wouldnt that be in the engine though? the noise and vibration is coming from right behind the dash.

my old 33 used to do the same thing but did nt do it when its on air direction face and feet i think its the cogs that change the direction of air flow

My 33 does the buzz click thing. dont worry about it everything still works ok!!!

I'm too lazy to even look

[SECURITY]

yeah but my problem is the loud and heavy vibration im getting from the left hand side motor

bearings in the aircon compressor maybe.

[SECURITY]

wouldnt that be in the engine also?

this noise and vibration is definately coming from right behind the glove box

Sorry, when you said motor, i thought you ment engine.

[SECURITY]

oh sorry.. i should've said left hand fan outlet

[SECURITY]

anyone have this problem?

im pretty sure its to do with cogs behind the dash with missing teeth.. When it tried to move it slips around.

thats what my old mech told me.

[SECURITY]

so to fix it i have to take my dash off or is there another way to it?

if it's the motor that drives the vent control (ie floor | floor+vents | demist)) you can replace that without taking the dash out. Not too difficult to do,just awkward. As for the noise on the passenger side, could it be the nearings in that fan worn out? I think that's (ie - the passenger footwell) where the air is sucked in from when you put the A/C on recirc.

[SECURITY]

can you give me details on what im meant to be looking for and where?

ive had a look under the passenger side and theres alot of crap all over the place.. i wouldnt have a clue what to look for

I have no idea what the fan looks like on the pass side, but i'll try and get some pics of the vent motor for you

i have the same problem on my r33

i get a click noise as soon as i start the car which i think has nothing to do with the air con (because its not on) maybe starter motor,

It sounds like scretch noise, and then when i turn on the air con i get that whizzying noise your talking about

I have no idea what the fan looks like on the pass side, but i'll try and get some pics of the vent motor for you

thanks alot for that. that would help me out alot

i get tht click whizz noise too, on cold mornings i notice my hicas light will flicker on off for a second or too (before i kick over the engine). So i guess its either the power steering pump repressuring or something along the hicas lines.
