The low pressure cut out switch located in the larger refrigerant line (the low pressure side) in front of the evaporator (passenger side, under the hood) may be sensing low refrigerant. Also the low pressure switch may have a bad electrical connection or the switch may be going bad.

You probably replace the wrong switch. I believe the high pressure switch is mounted in the back of the compressor. Pull the plug and jump it. If it works, replace the switch. I don't recommend you leave the jumper in the plug. If it the A/C pressure is to high, you could blow lines and such. Costing you a lot of money.

Blows cold when first started and then blowes warm


I would replace the AC compressor cycling switch it may be sticking have seen it a number of times. The switch is located in the receiver dryer on the passenger side of the engine compartment. See picture below.

If this isn't the problem the AC compressor relay may also cause this, flip a coin.

My toyota corollas (2004 LE) a/c blows out cold air for 10 min and then starts blowing out warm/hot air. Filled up freon but it did not work.


Sounds like your HAVC pressure switch is going out cutting off prematurely or the system is overcharged and shutting off to prevent damage.

Heater does not blow warm or cold ....you can feel the air but does not blow


Had a similar problem with my friends 2002 Silverado, first the blower motor started making funny noises and then quit working. Cost $45 to replace.

Before getting a replacement, check fuses and relays related to that circuit and make sure there is power going into the blower motor.

Good Luck

Cold air on the Driver side warm air on thepassenger side


You probably need to replace your dual climate control valve (aka Heater valve) This regulates how much hot coolant each heater core gets. When it malfunctions it either doesn't turn on or doesn't turn off. So either you get limited or no heat on one side (or both sides) or you get warm air when your ac is on, usually out of one side and not the other. Mine went out at 50-60K and I had hot air blowing on my feet in 90deg weather. If you are not under warrant I would recommend purchasing one yourself and taking to a trustworty mechanic. It only takes about 45 min to replace but the dealer will charge you several hundered for the unit plus several hours of labor. Rockauto sells them for about 170, I managed to find mine online a couple years ago for 115.
Good luck
