Good morning,

i need some advice, i recently got the system vacuumed and gassed (with the new gas as i was told they no longer make the one that originally came with the car). i have not used it that much as i had an issue with the idle on the car, that has since been sorted out. the other day i was using it and found that it was not blowing cold, did some checks and saw that the fuse was gone, changed it and as soon as i switched it on the fuse was blown again. changed it and disconnected the current to the compressor and used a tester the light remained on and the fuse was good. so i plugged back the current to the compressor and the fuse blew. So i know it is the compressor is the cause. so i have a few questions. ps. the compressor wheel spins freely

1. could the use of this "new gas" caused this

2. is it that the electrical components in the compressor need replacing (is this possible like an alternator) or do i need to buy a complete compressor and replace.

some other information. it is a complete R32 gts swap that was done on the cefiro, the fuse being used is 10amp

thanks

Roger

Before you go replacing stuff check your wiring, usually when fuses are blowing it is becasue you are grounding out somewhere.

Check the wiring from the compressor back to inside the cabin

Remember these cars are 20+ years old and have seen alot of miles and conditions so the wiring, no matter how go the condition you might think they are in, might have a crack or 2 in them so check everything!

Good Luck!

quick question, the ac compressor on the det has two jacks, i noticed that the electrician only used one and basically he just jacked back in the one for the original harness (rb20 single cam) could it be possible that both jacks needed to be hooked up? is it necessary, when i asked he said no. could this have caused the compressor to go bad and keep blowing the fuse?

Thanks

roger

      R33 general questions

      By Kaptain · Posted

      Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in

      R33 general questions

      What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.

      R33 general questions

      By Kaptain · Posted

      Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha

      Did tie rods. Steering now not "springing" back.

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
