How to Replace the TX Valve in the AIR CON

[Eav00l]

Hi all, my TX valve is blocked, and i have no idea where it is or what it looks like, im told it will either be in the engine bay or under the dash.

Does any one know/how i can get instructions/help on this issue for relitivley cheap? i know replacing this valve if its under the dash is a pain in the butt and can be expensive, but sumnmers coming and i cant wait any longer.

if you are in sydney and have done this before i will pay you to help me do it.

Thanks all

In the R33 the air-con evaporator core is behind the glove box.

Remove the glove box

Unplug anything that connects to it

Remove the 2 black clips that keep it together. (one on each end)

Undo both lines into it. (from engine bay)

should just pull out.

The TX valve sits on the core

thanks mate, i know this may sound dumb but would you be able to specify where the black clips are and what the TX valve looks like

or will i notice it str8 away.

any ideas on the cost of a new TX valave

i think you would need a professonal to do this as it is part of the air conditioning sealed system.

i could be wrong though.

yer best to get a pro.. as u sed its a sealed system and u dont want any moisture in there. plus u have to take all the gas out and vac it.

just get in there with a 12" and bash the **** out of it to see if it opens up.. its either stuck or blocked so just whack it

Once you pull out the glove box you will see...

There are a couple bolts that hold the unit onto the firewall, and jus the clips that join it to the other ducting.

A plug here or there on it too.

It is simple to get out, if you have a bit of a clue you will find it easy too.

well as being as air con fella my self ive found that a air con system i presurised so if you gunna go crackin valves or fittings be prepared for a lot of cold cas and a bit of oil exiting the system

i would get a pro to vac the system a colect the gas

it aint hard but there probaaly is a reason its blocked as in something got stuck in it

so you might wanna look into it a bit more than just replacein a tx valve

just my thoughts thats all

when i first bought my r33 the air con didn't work because it was missing the belt. So replaced it and went to get the A/C regased. The guy at aircon place told me that now the compressor was caktus. I was told this was due to the tx valve blocking up and causing back pressure and resulting in the death of the A/C system. So ended up replacing the tx valve, the dryer unit and the compressor and obviously a regas. All new parts ending up costing 1000. But to me anyway well worth it rather than risking a second hand compressor unit.
