Hi Guys!

I'm having problem with my climate control unit, it died all of a sudden. Checked the fuses and relays. The buttons light up with the headlights but nothing on the display nor any of the functions work, including the re-circulation and rear defrost.

I have noticed another post from a few years ago on the same topic but there was no solution mentioned.  Any other ideas? 

Any help would really be appreciated! Thanks!!

"Checked relays and fuses"..... does that mean you broke out the multimeter and probed the connector on the back to ensure that power and earth are actually present on the unit itself? Checking fuses is only the very first step in the process.

Well, I checked all the fuses in the fuses box and they were all good. I swapped the A/C relay with a known good relay and the climate control unit was still dead. 
I have not checked the back the climate control unit with a multimeter for power as I do not know which terminal/wire should have power when it’s supposed to.

Oh I never fit any parts.  I just order them and put them in various piles in the shed!  I've spent more money on parts on my car over the past 10 years than I bought my car for and the majority of those parts are not in contact with the car!

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
