Hey Guys,

Couple days ago I used de-mist on the climate control to clear the windscreen and ever since, moisture/steam has been rising from the air vents along the base of the windscreen, fogging it up and causing water to drip from the glass, I cant see shit. Has been happening for a few days now, smells nasty and making it pretty difficult to drive.

I assume its related to the A/C -Condensor or whatever, just wondering if there is anything I can do to make it stop without having to take it in to the shop.

Any help appreciated, cheers.

Tristan

Have you checked the coolant?

Could be the heater has a pressure leak... but I would imagine you would notice a few other things at the same time.

Can you feel if there is any air flow from the vent? If so, is it hot or cold?

The radiator coolant?

Yes the air flow is hot, probably why the window *fogs i suppose

Like eiji said it sounds like a small leak from the heater core, maybe check the coolant level, get it pressure tested and see if theres any coolant leaking from the heater box, if there is then its heater box out, big job on most cars not sure about yours though.

Best thing to do is get a pro to take a look at it. Get an accurate diagnosis :D

Thanks Guys,

Seems I can bypass the heater core fairly easily by connecting the inlet/outlet pipes together. Might try that rather than spending hundreds replacing it. I found a tutorial on replacing the core without having to remove the dash, will try when I have the time.

Cheers

In case anyone is interested, I have bypassed the heater core and the problem seems to have stopped. However, as the heater core was rusted out, the coolant/rust is now throughout the cooling system, I will need to flush the system.

So for future reference, if you notice a problem with the heater core, dont leave it.

      You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there

      A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not

      GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣

      Yeah Jap import. Fairlady Z then! I'm a bit the same.  They've been on my radar for a fair while but then just impulsively decided to buy one!  Was going to just buy an NA and add turbos to it later but decided to save the f'ing around and just buy the turbo version.
