Air conditioner comes on for 5 minutes then shuts off for 10 min
I have a 2000 Limited and I have had the AC system Charged.. The thing is it only lasts for 5 minutes... then it takes 10 minutes to thaw out the ( condensor ) Im guessing.... What could be doing this? Expansion Valve or low-pressure cycling switch? I bought a Hayes Manual and it said it had no detailed info and to buy the air conditioning book by Hayes... WTF? LOL,
Re: Air conditioner comes on for 5 minutes then shuts off...
Freon charge low, bad evap cycle switch, dirty evap Car has a fixed orfice for its metering device. ac cycles on low pressure around 32 pounds. you need gauges to see what the evap is doing to determine if its low charge of switch

if the ac system is very strong and there a lot moisture in the air the a'c evaporator core will freeze up and stop air flow threw the cold core only use the recuiculation part to cool the car down about 5-10 min the turn the recuit off
you say it will blow cold and hot air for only a few minutes. You don't say but I assume you mean will blow cold a few min. when turned on AC max , blow hot only a few min. when turned to heater hot. Assuming thats the situation and you say AC charged and shows good on the low side -you should charge the AC to a full charge on the low side will cause problems with the AC air compressor kicking on and off. I suggest while the engine is running and turned to AC cold max watch the AC air compressor clutch to see if it does indeed kick on and off if so charge completely. As far as the heater make certain you coolant is all the way to the top and the best way to do this is when engine is completely cold remove radiator cap and fill completely and completely close cap then fill overflow container just to the cold level. That should fix your problem.
My 2001 limited did the same thing. I bought a refridgerant refill kit from Walmart and plugged it in, but it showed that the level of refridgerant was fine. Turns out the AC belt had come off. I found it laying in the skid plate. My auto shop charged me $25 for a new belt and putting it on.
If you are positive it is full, then I would have someone check the pressure switch on the evaporator. When the system pressure drops, it will shut off the system. Usually people think the system does not work when I buy a car, and 9 out of 10 times it is just not fully charged. I wish you luck and have a great day.
'64 could be right, but these Malibu's also have a tendency to go through HVAC head control units, among other things. I have taken the head unit out of mine and cleaned the contacts, etc...with some success. However, from what I've seen, this is just a temporary fix. These units run upwards of $200 at a dealer, but you can get one online for just over $100. It is a really easy install.
Other common problems include:
-Cruise control modules going bad (cruise kicks off at will)
-Bad resistor on fan blower (only speeds 3-5 will work)
-Front coil springs breaking
-Front brakes wear funny, excessive wear
-Moisture in headlight housings
