Is it really necessary to have the AC condenser fan on when the ac is on? My ac is in working condition but my fan isn't. I don't know if I should drive with my ac on if the fan isn't work. any suggestions, this is on my 99 civic ex if that makes a difference? Thanks

 

the fan is there to reject heat.

w/o a cond. fan you'll trip the high pressure safety switch when the car is idling.

 

hmm, when my car is idling for like 10 mins without the condenser fan, my compressor starts to throb, like rockin back n forth. do you think its from the condenser flippin the high pressure switch that cause that to do that ? or is it just a bad compressor?

 

 

the fan is pressure activated, when the high side pressure reaches something like 140psi, the fan will click on and i believe it will shut off around 115 PSI. Idiling has nothing to do with it, it's pressure activated, and if it doesn't come on then your system will reach a high pressure and the pressure switch will shut down the compressor.

 

ohhh, thanks a lot man!

 

great way to kill the compressor.
