aircond fan(aux fan) fix

[moots]

well...my ac fan was not running as it shud.it runs at medium speed when the condensor heats up and cycles on and off.and runs at hi speed if the engine is real hot ie it acts like an aux fan.but recently even the medium speed osso don't work.so after reading up,the ac fan is supposed to work at slow speed when ac is on and medium speed when the condensor heat up and hi speed when the engine hits hi temps.the cause is the 2 power resistor located on the fan itself.called bav auto and was surprised they have stock.didn't change as a whole harness assembly as it wud be too messy.so instead i spliced in both the resistors and hey presto....the fan works as how it was designed.quite expensive at rm215 but beats a second hand fan at rm300 and new fan at more than rm1k.

Moots...

What was the symptom to your ac performance...? car stop ac tk sejuk.. keta jalan baru sejuk ke?

actually i just so happen to notice that the fan was not running after some idiot reversed into my car,pressed the kidney grill into the fan blades and stopped it from running.this blew the #7 and #22 fuse...(inside glove box)

even after replacing the fuse fan still won't run.....

so i then bypassed both resistors and replaced fuse 7 and 22.fuse 7 blew straight away.the fan ran at full speed and cud be heard miles away(like merc fan of yesteryears) and cycles on off like jap car fan.

after doing this power resistor repair,i replaced the #7 and #22 fuses and all worked normal again....

good info bro moots !

what the value for either of the resistors and wattage used?

 

[moots]

hi bro jarance,
0.5ohms 85watts and 0.2ohms 80watts

Thank you, Mr Fix-iT..
