SOURCE: idling problem when ac turned on honda civic lxi 1999

Hi,

To my knowledge (at least in my country), some Honda Civics have a compensator solenoid the pushes on the throttle that adjust the engine's RPM to its standard idling when the A/C compressor is activated. Technically, this solenoid is nothing more but a coil and a plunger. When the compressor runs, the same relay activates this solenoid and pushes the plunger forward increasing the RPM. Pls check/clean/adjust/replace as deemed fit and necessary.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

I lost the link for this thread, Thanks for posting ED. There was some great help on this problem at this site. the fault ended up being a thermal fuse in the fan speed control moduel (black box in the a/c ducting next to the fan) $3 fix!
