Daston Posted January 10, 2007 Share Posted January 10, 2007 Ahh just dropped my bro home (40mile round trip) and my heaters arnt working too well, if they are directed to the screen then the drivers side vent is warm (and changes temp when I turn the nob). However if I switch it to face or face/feet then it blows cold air or emits loot warm air on lower settings. Any ideas sounds to like the controls or is this the dreaded matrix?

merckx Posted January 10, 2007 Share Posted January 10, 2007 If you can change the temp from cold to hot wherever it's directed then the matrix should be okay. Worth checking the matrix if you cannot do this, coolant level dropping, damp floor mat,excessive condensation in the car. Link to comment Share on other sites More sharing options...
Daston Posted January 10, 2007 Author Share Posted January 10, 2007 the car has been quite misty the last few days but I put that down to it being cold outside Link to comment Share on other sites More sharing options...
Daston Posted January 11, 2007 Author Share Posted January 11, 2007 Right been searching the forum abit about the matrix I am thinking that it could be either an air bubble or blockage (I pray I am right) I think this as there seems to be a few other problems that I have over looked. 1) Cold start RPM is around the 1.9k-2.5k figure this seems too high 2) Warm Idle sometimes drops to 400rpm and is very lumpy 3) there is warm air there but its rather loot warm and only if it dosnt come out on setting 3 or higher. 4) wird one this but the foot well heaters are not blowing at all no mater what setting they are on. Any further ideas would be good. This always happens to me my cars must know that they are going to be part ex'ed or sold and so die on me! I am half harted to go to the nissan dealer down the road and buy a brand new 350z! Link to comment Share on other sites More sharing options...

Bob Posted January 11, 2007 Share Posted January 11, 2007 By the way way, it's "luke warm", not "loot warm". Sorry for being pedantic Link to comment Share on other sites More sharing options...

Scooter Posted January 11, 2007 Share Posted January 11, 2007 with it up to temp and the heater on, have you felt the two pipes that go in and out the bulkhead? Within reason they should both be as hot as each other, are they? Link to comment Share on other sites More sharing options...
Daston Posted January 12, 2007 Author Share Posted January 12, 2007 not yet I will do this tonight,. Are these pipes the ones that are on either side of the engine bay at the back going towards the fire wall? The only ones I have seen are on a TT engine Link to comment Share on other sites More sharing options...
Daston Posted January 12, 2007 Author Share Posted January 12, 2007 Right guys ended up taking the car into town so thought I would have a feel around when I got back, theres 2 big pipes that go into the fire wall close to each other one starts off as a metel pipe and then changes to rubber the other one is rubber that sits on top of the engine with foam blocks. Take it there are from the heater? Any way the one ontop of the engine was very hot could touch it for a second or 2 before having to remove my hand. The Other pipe was also hot but not as hot as the other one. Is this good sign of a block and shall I flush it? Or am I a numpty and holding the wrong pipes?

Daston Posted January 12, 2007 Author Share Posted January 12, 2007 Ok out of interest I went to check my water levels when cold, It looks as if my coolant has gone from my rad! Plus my expansion tank seems to be rather full. Any ideas would be good Link to comment Share on other sites More sharing options...
Fifty Posted January 12, 2007 Share Posted January 12, 2007 Might be talking shit but sounds like air lock to me from an earlier post by ardsaliah The easiest way I've found of bleeding the coolant system is to let the expansion tank do the hard work. You have to fill the expansion tank about 3/4 full of coolant, and when the system warms up air gets vented into the expansion tank as it's pushed out the rad and it bubbles off, and when the system cools down it sucks coolant back into the system from the expansion tank. With an 'overfull' tank it always has fluid to suck back in. About 2 or 3 cycles like this and your airlocks will be gone, but remember to have the heater on full heat so that the heater matrix is actually in the loop, and you may get some coolant sprayed out of the expansion tank, which is normal for this procedure and nothing to worry about.

Scooter Posted January 12, 2007 Share Posted January 12, 2007 have you looked in your passenger side footwell yet? from memory its just a couple of plastic poppers to release the carpet........... I only say this as it seems like you are losing coolant somewhere and i'd check here first..... Link to comment Share on other sites More sharing options...
