Question about 1994 Hyundai Excel
Well, this is correct, but this did not happen before. The normal function is the fans work only when ambient temperature is high or ac is working for some time. Now, fans work very fast at morning, when ambient temperature is low and after engine pass all night off and stays cool. At morning, I just start the engine, push the ac button and the fans start run very fast, immediately. This is not normal. If you know what is the problem, please, help me. Thanks.
Ok there is a relay in the power dist. box for the a/c fan it has a high and low side or there may be two diff. relays what I usauly do is swap this one or them for known good ones check part numbers swap from i.e fuel pump power window and such if that doesnt work you most likely have the winding in the fan motor itself fused together basically worn out to check this use a ohm meter check across the pins in the fan side of the plug with it unpluged only two at a time should have flow black wire is ground leave and usually in the center check the other two without take the negative of the meter off the ground both should have continuity now check the other ones negative to one hot and positive to the other hot if these have continuity you have a shorted fan motor it needs replaced.. let me know if this works or if you need clarification thanks Danny

this not really a problem as the fan speed is controlled by the high preasure switch in the ac system the hotter it is outside the higher the preassure will be in the system as hot as its been the preasure is high already when the compressor cycles it pulls suction on one side and outputs high preasure on the other the fans cool the condenser the higher the ambient temp the faster they go so all is fine...
