Hi.

When i have the blower on blue posision, my ac is coming on and off continuesly every 1-2 sec. This causes the fans to start and shut down as well. This causes allso that I have an ideling problem. Idle when ac on, is 1100, and after i have accelerated and take the foot off the pedal, the engine slowly creeps down in pulses (like the fan issue) from 2000 rpm to idle.
This is happening some times when the fan is turned on the "non ac"
I do not know if this has any relations to the other things.

When the blower is off, all is normal. idle at 900 rpm

The throttle wire is not binding, just for info.

Sorry for bad english

 

Could be a stick IAC valve and or TB. Pull them together and give them a good cleaning.

 

The A/C on-off could be do to an undercharge or bad pressure sensor, Dont have a clue about the Idle though.

 

I have disconected the socket from ac pump. All is well now, expect for the AC is not working.
