In my case, it was a pretty simple fix....the trailer had been sitting for a couple years and the shaft for the blower just froze up a bit....with some redneck technology I got the fan spinning again and it works just fine now!!! sometimes the solution's are real simple!!!

Sound like the fan isn't running. This could be due to a bad capacitor for the fan, a blown fuse for the fan, or a bad fan motor. The capacitor can be checked with a multimeter. You should also check to see if the fan has power going to it. If not check for the fuse or a breaker. You can check the fan windings with the multimeter also.

Bad run capacitor or bad compressor. If you hear an occasional click from the compressor try a new run cap and then a hard start kit. Otherwise it's more economical to purchase a new unit.

1992 Dodge Dakota 2wd 3.9L V6 Air conditioning/Heater dosent blow? when i turn the air or the heat on i can hear the compressor kick on but it dosen't blow cold or hot? any help would be appreciated


Roger it sounds like the blower motor is not comming on. There is a resistor network located in the engine compartment on the passenger side mounted to the firewall, that controlls the blower motor. The connections may have corroted or the unit itself is bad. That was the first thing I had to relpace when I got my used 92 Dakota. There is also a 30 amp fuse in the fuse box under the dash board . If that is blown I would suspect the blower motor is seized up or just pulling too much power.

Air conditioner blowing only warm air


possibly have a capacitor out on the compressor side of the a/c Since the unit works and its only blowing air the compressor isn't kicking in. The capacitor boosts the compressor to activate the compressor. I would have the capacitor to the compressor replaced first before going any further.

Good luck on your repair

A/c unit is not blowing cool air. I took it apart and cleaned all the coils, but it still is not cool. There is also a sound like something is trying to kick on but it just kicks right back off.


sounds like the compressor is having trouble starting. this could be the start components or the compressor itself. if the fan is running when you hear the "kicking in" noise it is you compressor, they are generally PSC motors, that require a capacitor to start, the capacitor could be bad, or the compressor may need a start kit added to it, they are available to the public at most appliance parts houses, you will need the model and serial number of the unit to select the proper one.

My window Ac unit wont cool, I had problems with the cooling element icing over but now the ac wont kick on the fan still blows, and Iv only had this unit for two weeks.


You are low on freon. There is a pressure switch that will not allow the compressor to kick on in order to protect the compressor. The freezing up of the unit is an indication of a leak or air flow blockage.

Compressor tries to kick in but then stops.


it is a hard start compacitor, the unit is not supposed to have three compacitors.

Will not cool properly.


You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze

Cooling problem


Since it is not so hot outside you may have to adjust the Thermostat to a lower setting to get the AC unit to kick on the compressor and blow out cold air. Give it a try, and if not the T-stat then we can go from there.
