Doing heater Matrix and having trouble with Dash!

I've got a LOT of it out now, I'm down to the dash cover, the crash bar and the climate control box itself.

 

Everything is ok cept I can't get the FUCKING cover off at the top! ARGH! :swear:

 

it seems loose and I can't see any hidden screws but it seems loosely held at the top near the windscreen. I need to get this damn thing off, I'm going nuts and it's gonig to take forever to fix at this rate! :help:

 

I can get it back on one I know how it comes off without damaging it ;)

 

gonna have another go, help me sooooon!

 

thx guys!

ok, top is loose. it still seems held in neasr the back by mysterious forces. I'm suspecting all the wires bolted to it - please don't tell me I have to somehow unbolt them all.... :s

 

the left is free but mainly the centre and a bit the right it seems a little held down.

 

I've labelled the wires I can see....just need to get it far enough off to get to the crash bar n so forth :(

 

Look at this the positive way - once I've done this I can probably do anythin gon the supra without fear! lol

Got it! Thanks to Jez for that.

 

Freaky stuff.... I have pics that are scary :s you guys weren't joking when you said EVERYTHING.

 

the only prob so far is athat somehow one ot the nuts on the steering wheel column has rethreaded and it's loosened but will not undo - it goes reound easy enough but it wion't come down!

 

extreme measures called for >:D

ok, two things of great importance:

 

first, i discovered when I took the crash bar off that the rear two bolts are partially stripped. I think it will go back on fairly firmly... however, what's the best thing to do? I don't know how to rethread them and they are sorta WELDED on...

 

2) I'm suspicious that the original issue with my matrix may be in the joints - they don't seem the best design to me, and I've tried replacing the rubber etc but I don't trust the brass clamp things. Any suggestions ona quick easy way to make sure this will be good?

 

Anyone know a way to pressure test off the car? Once I am convinced it is pressure proof it won't take too long to reassemble to driveable point.

 

I HAVE to have this car running this week. It is needed for a wedding next saturday.

 

Help!

hi chris

Im pleased to hear your having as much fun as i did i changed mine a couple of months ago and it was a nightmare those clips also gave me hell. just make sure you have all the main dash srews (the gold coloured ones with the large washer near the head) in place when your done because i think i missed two of these and the dash buzzing like mad on the motorway.

I also had to do mine twice because like a complete :donkey: when i was rushing to get it all back together so i could get out that night i forgot to tighten the clip round the top of the matrix hose, to make things worse when i realised it was leaking again i took the top glove box out and could see the clip i didnt nip up :swear:but i as know it ALL has to come out again. how i didnt petrol bomb the car that day i dont know, but looking back on it now i suppose it was a good thing.

Good Luck and for christ sake tighten them clips, i dont think i could bare for someone else to go through it :cry:

Hehe yes I wanted to make BLOODY sure it was done.

 

I've repaired what I could of the fittings - seems whoever wired or whatever the car befoer I had it broke a lot of things :swear: but it's all looking good. I reclamped the matrix, wrapped rubber tape under the clamps to makes doubly sure, and replaced hoses n stuff.

 

Got it together last night - it ran!! Just need thermostat replacement and to recharge the a/c!

 

I can't believe I did the matrix myself, I didn't have a clue WHAT I was doing lol I'm a computer engineer, not a mechanic!

 

I actualyl think it might be ready in time for the wedding saturday!

 

It has taken me probably 25 hours of work to do it and the rad and put it all back and test. Unreal, but Damn do I feel good I can do it. I'm in the elite club of heater matrix people now ;) :thumbs:
