Aircon Problem

[CMF_Radiolite22]

Hi guys,

Recently got some air-conditioning issue on my 96 3dr micra.

There are no air coming out from the aircon vent when switch is on. My mechanic says it's due to overheating of the engine area which causes the fuse to melt. Changed the fuse to 15A and it melted when aircon is turned on. Tried the 30A one..still same situation.

One mechanic then suggested fitting a relay switch box to "control" the voltage to the compressor...My friend who drives a 5dr micra advise against doing so as it may cause a overheating in the electric circuit board... may cause more problem to other electrical parts instead...

Another mechanic say aircon compressor is faulty...needs replacement.

Dunno what to do now... PLS HELP!!!

by no air con..you mean no wind or no cold air. and also you should never replace a fuse high amperage than standard..its set for a season.

have you checked if the ac system is gased? is therss no gas the low pressior switch in the compresser wont turn on as will damage the compresser.

There is no wind.

I do not know about the ac gas as the wind was cold before it malfunctioned... totally no wind coming out from the duct.

When I went to a local scrapyard searching for a used compressor, the staff asked me if I'm looking for the one with green gas or the one without...Mine is a 96 3dr LX micra on a CG13DE engine... which one to get???

green just means it has fluroescent dye in it for leak detection. dont know what the laws are over there by in aus u need to have R134a gas. there should be a label somewhere under the bonnet that tells you what gas your system takes.

yeah green is just a dye mine is yellow...does you fan work on full might be the resistor car.

so how do you fill this dye thing, because my condensor was changed and all the green stuff was spilled...

You probably don't have an aircon problem. If as you say your not getting any air blowing out from the vents when you turn the fan on then it's the fan or it's controller card that has failed.

the dye can only be juiced in when you gas up the system and also if your blower doesnt come on even on full then the whole blower is stuffed.

blower fan is comes on, AC led ON, but not getting cold......so does this mean i only need gas....

most likely just gas

Problem is the aircon fuse kept burning out. Wind comes in and cold air comes in when I replaced a new fuse, but only for a short while before fuse burn again...

Wat could be the possible problem???

get an auto electrition to check it out...ive had bad experiances whenn comes replacing and up rating fuses.
