1988 nissan sentra air conditioner. Electical problem
No power to the switch inside the car. Engine condenser fan won't turn on. All the fuses are intact. The systems pressure is at perfect levels. Before This happened I was working inside the car. Working on the dashboard. Not 100% sure using the right wire for the switch, but there are no other wires that fit it. Something is disconnected somewhere or there is a short. Last I was also working on the cooling system and antifreeze spilled on the condenser and fan area. The inside switch does not light up at all.

My 1988 Nissan AC quit working soon after having the compressor & ect replaced. AC Tecnition took the switch box out from under the dash and cleaned it. He also fixed a loose wire in it. He said this cars switch box calcimates and does not make good contact. AC works great.

Let's start with the passenger compartment fuse box. If you checked the 30A HEATER fuse the blower motor should run at various speeds as you operate the blower switch. If you checked the 10A REAR WIPER fuse (!), and also checked the 30A ADD (?) fuse in the engine compartment fuse relay box, turning on the air conditioner should operate the A/C relay to turn on the condenser fan motor. If this doesn't solve your problem, you'll have to trace power through the various circuits.
Need to make sure the fan is acually running with ac on.If so see if the fan is pulling air,or pushing air.Is the fan on the out side of condenser or inside?The fan ,if on the inside of condenser(engine side)it should pull air.If it is on the out side of the condenser it should push air.If all this checks out,then see if the fan is running slow,it should run very fast.Is there another fan?Is it working?It to should be running with ac on.
Not all switches switch the possitive side of the electrical cicuit, sometimes it switches the negative side and than you wont find current there. The airconditioner unit has a low pressure switch in the system somewhere in the pipe that monitors the amount of gas in the system and if the gas is not enough the switch will not allow current to flow through to the compressor, it is just to protect the compressor from siezing up if there is no lubricant in the system
