SOURCE: nissan 2000 ac hot when idle
the a/c condenser has a fan in front ( there is actually 2 fans if you sit on the car it will be fan on right side ) if this fan does not
come on immediately when you are parked and engine in idle
there is a problem with power to it, or motor failure. If you drive it
on the highway and a/c operates fine that's because air is circulating though condenser (thats what the fan is supposed to do at idle or slow traffic)

It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.

This may be because your cooling pump is either cam or belt driven from the engine rotation, the faster the engine revs at, the faster and better the pump pressure is.
The higher the pump speed the better coolant flow is and the heat exchanger can work better at cooling it as it is cooled faster.
Therefor, the faster you drive, the better the output, but at low idle revs, the performance is affected - not ideal if you are sat in traffic on a hot day!
Some people consider having the pump changed to an electric motor drive, but this can be costly and not really worth it.
Hope this helps.

I've had mice in my Nissan PU and actually caught one in a trap set on the floorboard; so I know they can get inside. They also knocked some of the fiberglass insulation into the blower motor so it vibrated as it was no longer balanced. You could have a dead one in your blower. Mine was easily accessible from under the passenger side under the dash. Three screws and the motor dropped so I could clean out the fiberglass.
