Re: I bought a sensor for the ac because it wont throw...
If it is near the radiator it must be a high side clutch cut out or highside fan switch/follow small ac line/hose out of ac compresor ,it should go to condenser the witch is probley in that line

Make sure the radiator fans come on when the AC is running. They MUST be running when the AC is on because the controls apply power directly and do not use the temperature sensor to start and stop the fans.
You really do need to burp the radiator after replacing it, but that should make the A/C not work. I suspect there is a connector that came off of a pressure sensor on the A/C condenser. That condenser is right next to radiator.
check if you have enough freon gas in the air conditioning system so as to get pressurized and by doing so the fan should start. Visit a prop[er air conditioning fitting and service garage for help.
What was the "flaw" in the friends AC system that took two years to figure out? Maybe yours has the same "flaw" and it's taking 4 years to figure out? Don't expect your AC to blow ice when the ambient temp. is 100 degrees and you are stuck in traffic. It's not going to happen... If your compressor is weak and not compressing properly, efficency goes down. How many miles on your truck? They wear out, like any other moving part. I suggest you have a complete evacuation done with a deep vacuum, this will remove any air or moisture. Recharge to mfrs. capacity. Clean the outside of the condenser and radiator of all dirt, debris & bugs so air flows freely....Pressure sensors and temp. switches can be tested, if they are bad, replace them. I hope this helps.
Take a look under the dash at the heater/ac blend door(s) and cycle hot to cold on he dash heat control while asking for AC and the vehicle running.Do the doors move fully?
You may be able to manually help the door move to get cold air.
The a/c should throw any warning except not be blowing cold air if leaking. The coolant/radiator light no most cars is simply the reservoir is low or the sensor is bad. The car wont light up a warning or can tell if coolant in the radiator is low, only if it's overheating form the coolant temp sensor to the ECM. Check all fluid levels. Check cooling system for leaks and if you find fix immediately, will cause major problems later and will start with constant air pockets in the system.
Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.
Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.
well my 94 just blew a belt and they all seem to run on the same main pully. As i just learned these belts need replacing, especially the timing belt. its only good for 70000 miles. If its beyond that and the timing belt gets strecthed even a 1/4 inch it can throw off the timing and much more and make your car turn pretty gutless. If the timing belt brakes, there is a good chance it can permanetly damage the engine valves. If the timing belt is weak, it may affect idle when the ac needs to be turned as well?
