    Default AC Blower Turns Off Automatically [ Honda City 2000 ]

    Hi fellows,

    vehicle under consideration is a Honda City 2000, and problem runs like this when i turn on the AC on any speed of blower after like 10 minutes blower shuts off, and with it AC also dies and AC clutch dis engages, wait for like another 10 minutes and it will turn on automatically, like its been programmed to rest for some time, running and idle time of blower at start of season was long and now its been reduced to like 10 mins or even low. blower is installed with a relay, its a nissan one 4 pin blue color, today plugged in a toyota denso one for testing but same, AC system is not installed with pressure a switch. today also opened up the center console to have a look at blower speed selector switch but it didnt shown any signs of heat up sorta thing, grip was snug and shiny connectors apparently it seems good too.

    so guys have you faced such situation with hondas or have any clue to pin down the problem, feed back and suggestion are highly appreciated.

    Regards,
    Mahmood

    Check the wiring at the speed regulator near the blower case, also check the wiring at the ignition switch and the contacts of the switch itself. btw where is your installed relay tapping power from? switched or live?

    The A/C is wired up as such that if the blower is not working the compressor wont run.

    now how would i recognize a speed regulator? isnt speed regulator built in into the blower speed selector switch? relay is tapped from existing switched supply i guess coz i see no external wire but not confirmed and i didnt get how ignition switch is involved, rest connectors on selector switch was in perfect condition.

    last line is a yes, i mentioned just to emphasize that it behaves just as if have turned off the blower while keeping AC switch on.

    Update: blower have exact same behavior on heater, so i think we can exclude AC system from the problem and safely put blower setup to the trial

    Just the blower switch buddy! You can try jumping it for a while to see if it shuts off. If it doesnt replace the switch if it does check further

    i also doubt same, and do you mean by jumping it that i remove the grip and short the terminals of the grip? if so i think not a bad idea. and whats the purpose of article at index 6 in the following diagram

    The relay or on/off switch has got a loose leg or point .. the sparking heats it up and the metallic point or leg bends to disconnect the connection and when it cools it comes back to its position short circuiting again ... a far fetched idea but could be the cause of problem

    i had something similar in mind but with speed selector switch but its grip is snug and no signs of heat up at all, all connectors are shiny. plz explain what you are referring to by relay on/off switch, as relay is turned on/off by speed selector switch itself.

    I'm not referring to any switch or relay but this is a common problem that occurs in electronic appliances .. in your case anything that has a make/break type action and has metallic contact points (the ones made of steel are more brittle and have the tendency to acquire exact previous shape after cooling) can be the culprit

    the ac switch (internally) has two steel type metallic strips which make the contact .. from the outside it would appear normal .. but constant usage makes the contact gather carbon and then the sparking and finally a melt-down, this is visible only when the switch housing is removed

    @naweed

    you are right and i guess as @fahad suggested i shout jump start the blower and check, i think thats the only way to islolate the problem part either to the selector switch or something beyond that.

    the speed selector is inside the blower casing, its a set of resistors that make the blower function at different speeds. It can show symptoms of no output when it heats up if its bad.

    There is also a subharness at the blower motor connector - check that if its bad or melted.

    Does the A/C button light turn off when the blower shuts off?

    yes, and do check the A/C button, this could be happening.

    blower start - A/C compressor start
    blower off due to wiring problem - A/C compressor running
    blower still off - A/C compressor trips off due to the evaporator temperature going to freezing

    Check thoroughly and systematically.

    i dont think so, if it would have been the sensor it will shut off the compressor abruptly and not the blower, here blower shuts offs. what exact was your scenario

    ok ji herez the update,

    i am ruling out resistor to be culprit here, if it would have been bad my blower should not work at certain steps or at worst case would run only on full speed, so thats good, selector switch i will be testing on sunday i guess but had prices from honda for both parts, blower resistor is Rs. 1700 something and heater switch assy is Rs.1100 something.

    Default update

    today jump started the blower by matting the terminals of blower fan speed selector switch but same behavior remains, the wire also got warm during experiment, whats next guys any clue

    @xulfiqar
    got one bulb for the AC switch and light on the switch does not goes off when blower trips, checked the AC clutch and it remains engaged contrary to my previous writing, but question remains if this is related to AC electrical then why blower behaves same on heater or simply when it is turned on.
