[QUOTE="swampratt, post: 3799537, member: 15054"] Blower speeds up and or slows down . Check and see if your vehicle has a blower motor resistor. If yes you may need one. But first check battery voltage with ac on high and headlights on and turn on the hazzard lamps also. Basically doing a load test on the alternator. You should have well over 13 volts 13.8-14.8 volts with a vehicle running. Checked at the battery if you were wondering . Yes it is 134A system many Toyota vehicles went to 134A before the 1996 requirement year. My 1995 Corolla is 134A. Coolant line that is the fatter one under the hood should be sweating and cold when the AC is on. Sweating in this humidity is easy.. dry air a little tougher to make sweat. Check that and if it is cold and sweaty then you could have air mix door issues. That would allow heat from the heater core to mix with the cold air and would also cause slow air speed as it could be a mix door allowing air to exit the defrost vents and you would not feel as much in the floor or chest area vents. Good luck. [/QUOTE]
