R32 Gtr - Extreme Heat When Fan Is Turned On At 18 Degrees

[chubi]

Hi Guys

I was wondering if anyone can shed some light on this matter for me.

I was driving up from busselton in the morning (4am) which was a very cold morning back to Perth. I began by warming up my car and turned my fan (at 18 degrees) until the water temp hit about 60 degrees and i began driving.

I was driving along for about 20-30 mins until i noticed a burning smell coming through, because i had a passenger with me i didnt want to alarm them by winding the windows and down. So i just turned the fan off and told them that the smell was coming from outside.

After another 20 mins i could feel the cabin getting warmer and warmer so i cranked the aircon at 18 degrees but was blasted with hot air instead, so i preceded to turn it off once again. This time when i touched the centre console, i realised it was really hot, my shift knob was hot and im guessing the panel next to the clutch which is a firewall was very hot too.

During this time, my water temp stayed at 76 degrees, however my air temp rose to 45 degrees. Eventually i cranked the heater at 32 degrees and opened the windows and the air temp eventually dropped back down to 35 ish and the centre console cooled down and there was no burning smell. Also my overflow cap for the coolant had been lost prior to this happening (it was screwed on when i went down to busselton).

Im in need of some wisdom as im not that knowelegable with cars. Any advice will be appreciated.

Have you done a diagnostic on the climate control system?

man if your not good with cars you gotta start somewhere, especially owning a 1990 one

what i think is that your heater tap is leaking aka your heater is always on

look up how to do a diagnostic on the climate control
