My buick century air conditioner doesnt work,i cant find the problem since i checked the refrigerant levels and they are ok,the ac compressor clutch engages and disengages,and the blend door actuator works since when i turn the temperature to hot it gives off hot air.What is the problem? It blows hot air at the coldest setting. ---

I only have the ability to check the low side and it measured 87 psi which is way too much.Does the high side need to be filled also? ---

No offense intended, but If you’re asking that question, then you likely don’t have necessary knowledge/ability to repair an automotive A/C system. Please take the car to a mechanic of your choice and get a proper diagnosis and repair. ---

Take your vehicle to a shop that does AC service. I can tell you lack the proper equipment and experience to properly diagnose the problem. Tester ---

+1234 for the above… No disrespect but A/C is better left up to the pros… A/C systems require proper knowledge and tools to do the job correctly, AND safely, over filling the system cam/will cause it to find the weakest point which can be a hose, pressure relief valve, etc etc…
