The comprehensive Air Conditioning thread.

I just plugged it in. No changes needed. As for the idle bump, I can tell you that the info is on this forum because I found it, but I can't recall the location.

My recommendation is to run a wire out to the harness connector, though, as this avoids the risk of hacking up the harness.

I believe its PIN 64 but lots of other folks were saying that there was no change in idle.

So.... How's the AC with a lightweight flywheel? Idle bump or no, I don't see this going well.

I am guessing lots of stalling?

[Danny]

Dunno, don't have A/c hooked up yet.

FYI:

Docblocks will no longer take orders on the individual blocks, they are out of stock.

Minimum order is 25 so this is up to distributors.

Damn i really need these things and i can't find them anywhere else.

Finally got some A/C lines and will start on hooking this up soon. I don't drive the car to work anymore cause its been so hot lately. I'll update if I have issues with idle bump.

[Supadave]

any issues with idle?

[cbusrehab]

Not sure yet, broke the condensor trying to get the old lines disconnected. New condensor is on the way. Maybe will have a chance to get it hooked up this weekend

[BDSax]

Ive read the threads but there isnt a straight to the point explantion. So using doc block requires no modifications to the e30 lines?? As long as your not using a seiko seiki?

Reason im saying is im willing to purchase the min amount and resell if people are interested. I want my ac working because florida is too damn hot.

Has anyone had success swapping compressor clutches for the purpose of changing belt style?

For instance installing a ribbed belt clutch onto an originally v-belt style r12 compressor?

[cbusrehab]

Hooked up the A/C this weekend, no problems at all with idle by wiring it this way.

Just wanted to update the thread here on the hoses. I got mine done at the local NAPA for just a hair under 90 bucks. Had to have ends brazed on to make the hose sizes the same. Tried to do the splicer route, but ended up with hose sizes that were NOT compatible with the crimps (thin wall hose, non-standard sizes)

Vacuuming it down now, after a very easy install. will see how well it cools with the new compressor.

new update today:

Car runs great with cold AC. Idle is steady at 600rpm with ac on, and NO wire hookup (slight hesitation when coming to a stop, but no stall, and smooths out instantly). Total charge needed, just over 1.5 cans R134a.

Update 4/7/12:

Went ahead and fixed the bouncing idle with AC on. The slight hesitation from above did not get better, and started to nearly stall the car out when starting up.

Simple fix, take the wire from Pin 64 on the DME (other end goes to Pin 6 on X20) and connect it to C136 inside your glove box (at least on mine) this is a violet/black wire that ORIGINALLY went to your DME for the M20 you have replaced.

I did not fish the wire out of the main harness at the DME, I instead ran a jumper to X20 at the swap harness. I dont like digging into a harness and possibly getting the wrong damn wire.

During test drive, the car still has a slight idle bounce when coasting, but is smoothing out with miles driven (adapting) Idle is 650 RPM AC on or off, easy peasy, lemon squeezy, took about 20 minutes to hook up.

^excellent info! I think I'll be going with custom lines myself.

[Dj Syco]

I went with welded ends and dave and I do that to all the customer cars, no complaints and no worrying if the machinist crimped the ends right. We've been tossing the idea around about having people send in their E30 A/C lines and we get the new ends and weld them and ship them back out for a flat rate. We're just unsure if there would be enough people for it.

[mammoth_e30]

bump for a good thread. Where are people getting their AC lines modified in LA or what kind of shop can do the work?

I called up the local NAPA store and the guy said he would just send my lines to Hose Express or some shit.

[CHITTY]

Danny wanted to check in and see how your ac is working since you had Adrian install it. I just picked up all the parts to install mine, and was wondering if you had any problems with Idle or anything else after install.
