If the air conditioner in a Mitsubishi Legnum is not working, there could be a blown fuse. There could also be a loose cable, or a problem with the heater motor.
For the Legnum, 6A13TT, it's best to use Fully Synthetic Oils, preferably 5W30.
The cabin air filter on a 1999 Mitsubishi Legnum is located behind the glove box. The filter can be removed once the glove box is released and taken out.
I believe it is 4.4 litres.
There are many websites that sell parts for the Mitsubishi Legnum. It is best to check reviews before trusting these sites though, as it seems that going into an auto parts store is more reliable.
The Legnum is a model produced and sold by Mitsubishi Motors. It is the equivalent of the Galant but is only sold in Japan and it's surrounding areas.
Replace the dash board.
Between $1000 and $2000
means you've got no gas haha
You can use 10W-30 weight motor oil in your Mitsubishi. A heavier motor oil can be used in extreme climates.
You don't.. unless you are Jesus. Let me know if you succeed.. :l
It does appear that one can upgrade the Legnum ECU although it is a complicated process. There are videos on YouTube to walk one through the process.
