The compressor is not cycling and the a/c is blowing hot air
Low on freon a/c leak and has set a low refrigerint code that needs to be cleared
SOURCE: dual climate control
There is a thing called a blend door, it controls air temp, that is where the problem is, most common issue is the motor that operates the door fails.
SOURCE: Air Conditioning cycles on and off quickly
hello,
had the same prob with my 98 blazer, i tested the conditioning system to see if i could just reboost the freon but he gauge was goin all over the place. if while the vehicle is runnin the compressor sounds like its shuttin off and on and then it needs to be replaced. you can take it in to get a diagnostic test if you dont wanna do it urself. the freon booster and tester is only $30 at a store... BUT hadx to get my system entirely replaced and it ended up costin $700...and now im leakin coolant.....hurray!
anyhow hope i helped......

Check the fuse for the A/C and try refilling the A/C with R134. You can buy the re charge kit at Auto Zone or Wal Mart, almost any Auto parts store. If the system is low on R134 the A/C compressor will not activate to keep it from burning out.
Try checking the fuse first then re charge the system with a can 12oz of R134. Just keep in mind not to over charge the system. Just follow the instruction and you'll be fine.
Keep me posted, be glad to help out.

Its a leak ...probably concealed like in an evap housing or rear air unit and lines (if it has that). Prob at this juncture I would remove all the freon and bring system into a vaccuum with a pump and see if it will hold vaccum for an extended period of time. A bad leak will not hold srong vacuum very long and much cheaper than wasting expensive and enviromental un0friendly refrigerants.
SOURCE: driver side heat blows cool air passenger side
Hello. The side that is not operating properly has a bad temp door actuator located up under the dash. I am assuming this vehicle has driver/passenger(dual)climate control heat and cold settings. This is a very common problem on these vehicles. Hope you find this information useful!
