[GTS-James]

Pull out the relay or fuse for now?

[GTS-James]

will that give me heat for now?

If you got no heat check the flapper door. (located behind stereo and can be seen from passenger footwell) Look for a metal rod and adjust the temp all the way up and down. If it does not move then you might need a replacement actuator. (Sometimes can be fixed by opening it up and resoldering the connections inside of it)

Is you're digital climate control working alright? When I first got my car my climate control was kind of on the fritz and I would get intermitent hot then A/C even though it looked like it was working ok and the screen lit up and displayed just fine. I popped it out and looked at the circut board. The solder on those things wears down pretty quickly. If you've ever done any kind of soldering re-doing some of the points isn't that challenging. I'm terrible at it and managed to get by. Works great now.
On a more crappy note, any chance your heater core is plugged, cracked or just toast?

I've seen how it works pump side when helping to remove, rebuild the aircon pump on my car. Aircon runs by supplying voltage to aircon pump which engages a magnet looking thing that connects the two parts of aircon pump together. Got the aircon pump from my car running to test output pressure, check for airleaks on the bench.

Unplug the power supply to aircon pump and it won't run all the time. Then sort the power supply problem to aircon pump later on. The plugs are on the aircon pump itself. Just unplug them and problem temporarily solved.

got boost- honestly im not too sure, im going to take it out and have a better look, but when i put on defrost the ac is on the screen and at 32 deg its freezin my nuts off.

and skym by temporary solve u mean it will work but its not the proper way to fix it right? also where is the aircon pump roughly lol,

I thought you had problems with AC pump staying on and not turning off or head unit for aircon pump is running aircon pump too fast thus making gas running through aircon pump, aircon intercooler that's located infront of radiator to be cooled more and causing air being circulated through aircon to be colder than normal. I was just saying to disconnect the AC pump to stop AC pump running.

Aircon pump is the pump that sits under powersteering pump on passenger side of engine. Or right side of engine if you look from front of car.

anyone know what fuse to pull to eliminate ac? or have a translation for a 89 gts-t fuse panel??? would be much appreciated.

Look at top of aircon pump, remove plugs that send power to aircon pump.

Here's a photo of a GTR aircon pump and can see the plugs I'm talking about -

Mine did the same thing man. Exactly. The screen would promise me all sorts of things, but I was actually running at the lowest temp possible and freezing myself out all winter long.
It's really not that hard to pull the head unit out and pop the top. You'll be able to see right away if the connections are breaking down.

[GTS-James]

will it be similiar to a gts one?

Cut your a/c belt

[GTS-James]

a solution that will not break more $hit is preferred:P

I really think you're going to have to have a look in the control unit yourself man. I know when mine went, I tried to find a replacement and a brand new one from Nissan goes for about $1100 :P If it's tuck on AC, then even pulling the fuse won't help. I mean, it'll stop the fan blowing the air, but the vents will still leak cold air all the time.
