AC blow fan in not working. tried to find fuse no

Which engine and transmission ? Needvinfo to look up wiring diagram.

if your engine is overheating could be the problem of the ac not working , check the temperature sending unit located by thermostat housing , if it is bad will not let the radiator fan come on when ac is on and will cause your high side pressure ac line to get to hot causing the high side switch to disable the fan , also check the blower motor resistor it controls speed of blower motor

Probably need an automotive electrician to find out why the fans don't work. When AC is on, the AC fan should be on constantly. Coolant has to get quite hot for the regular radiator fan to come on, but sounds like the fans are the problem.

Fuses blow because of higher than normal amperage in the circuit. Not sure what circuit the blown fuse is for but if it is for the fan the fan may be shorted therefore blowing the fuse. If you put fuse in while the ac was still on try shutting off the ac then putting the fuse in. See if it blows then if it doesn't then turn the ac on and if it blows you have at the very least isolated the system at fault.

CHECK THE AC AND HEATER CONTROL FUSE.MORE LIKELY FUSE BLOWED BECAUSE AC COMPRESSOR COULD HAVE FAILED IF LOW SIDE IS OVER 100 PSI. THE REED VALVE PLATE IN COMPRESSOR PROBABLY DAMAGED CAUSED COMPRESSOR FAILURE BLOWED THE HVAC CONTROLS FUSE. HAVE AC SHOP CHECK IT OUT.

Sounds like 2 different problems here. The ac gets warm when standing idle, is most likely the under hood fan not kicking on when ac is on. This may be a fuse issue or a relay. When ac is on, the fan should be on all the time. Relay maybe in an electrical box under the hood. Unplug the fan and test for power with a test light to see if the fan has power when ac is "on".

The inside fan not working on levels 1& 2 is likely the voltage ballast issue. this is an electrical block which controls voltage to change fan speeds. Usually found under the passenger side dash, right in the air flow comming from the fan and inside the air flow housing. Usually held in by 2 or 3 screws with a connector and 3-4 wires sticking out. this should be under $20 to buy and quite easy to change, if you can find it. Try behind glove box etc. Do not test the new one without it being in place, as it may burn out very quickly without the air flow to cool it.
Good luck

Sure. But could also be fan switch or motor. Check with a test light to make sure where the voltage stops.

check to see if ac compressor is turning ,if so look to see if cooling fan/fans are working if not check fuses,and cooling fan relays/if ac is turning and cooling fan/fans are working ,need to put gauges on ac system and check pressures ,if normal ,and ac low side pipe/lines/hoses are cols then it is ur actuator motor for the temp door that is not working

fan speed controler could be bad, fan motor rellay could be bad.

tom disconnect the battery for 5 minute hook it up and try it if ac work sometime computer shot out you disconnect and it reset the computer it hapen to me on my 98 540 good luck pierre
