If there's no click from the engine and noticable jump in the engine vibration from the compressor engaging then the compressor might be at fault.

The other common is the blend door being broken (sits in behind the centre stack and to the left of the driver side foot well) You can test it by quite easily by adjusting the settings and seeing if the door is moving. They sometimes pop of the ever that actuates them and sometimes they are busted.

See how you go and let us know.

cheers for the post,

tried the bleed door, seems to operate properly. i'm guessing its the compressor but i'm unsure how to fix myself and unsure who to take it to. i have a spare compressor off the old block but that needs a re-con.

cheers,

craig.

I just read my post, nice typos lol woops.

Anyway,

If it's not clicking/engaging then you'll likely need an air-con place to check it out. Ask a few mates see if they know or can recommend anyone and always ask for a quote before any work takes place. Be sure to clarify if the quote is free also.

Good luck,

hi i have a gtst, had a new motor put in regased the A/C and its still blowing hot air.

had a thought the compressor maybe shot because it doesnt "click" but would like some advise if anyone has had a similar problem.

Hey mate im a Refrigeration mechanic by trade i had the same problem as you on my R32 i got a hole in my condensor and lost all my R12 refrig is yours R12 or R134a also btw but with mine it was the climet control telling the heater to come on theres a heater solinoid behind ya head on ya heater pipes on the firewall in the engine bay repace that and ya should be sweet fixed mine anyways mate cheers ben

no other idea's anyone?

Run the climate control diagnostics first to see if any sensors are playing up. The compressor is switched on via the ECU which receives a signal from the climate control. I had the intake air temp sensor fail in my R32 (it read below 0degs) so the climate wouldn't switch the AC. Solution was a 10c resistor which corrected the sensor and allowed the AC to switch on.

If the sensors all check out ok, you will the need to check the pressure switch (in front of the radiator on drivers side) which protects the compressor when the gas pressure is low. Continuity across the switch will imply good gas pressure. If the pressure is low the switch will be open and won't feed power to the compressor.

Check the DIY section for running the climate diagnostics.

Hope this helps.

if wanting to do a quick check to rule out some main parts

1. check to see that when the a\c is turned on the entire face of the compressor spins

2. if first test is passed there are two hoses entering the firewall behind the stock turbo one above the other switch off and plug them off and join with a small pipe and hose clamps.

test the a\c again. if it cools you can rule out the compressor, the condensor, the dryer, the need for gas and a few other things.

if not you will have to resort to the previous problems stated in the posts

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
