Why does the AC blow cold air on the driver side?
Crank the vehicle without touching the climate control panel for one minute. After this try using the AC to check if it blows cold air on the driver’s side. If it is operating properly, the problem is with the actuators. If it is not working, the climate control panel is faulty. What could be causing climate control problems on the Buick?
What to do if your climate control is not working?
Instead a communication wire passes through all modules informing the HVAC module how the lights should be operated. However, since the problem exists only with the HVAC, it is the component to blame. The solution is to replace the HVAC control module since the lights are internal and cannot be replaced.
What to do if your car is blowing cold air?
The fuse is labeled HVAC. This should be pulled out for at least 10 seconds and reinserted. Crank the vehicle without touching the climate control panel for one minute. After this try using the AC to check if it blows cold air on the driver’s side. If it is operating properly, the problem is with the actuators.

Why does climate control only work on high speed?
There aren’t separate relays to mode control and the modes are switched by the climate control in the dashboard. If the fan is working only on high speed, it is probably a shorted blower motor resistor. The resistor is responsible for changing the voltage to the blower motor.
Why is the climate sensor on my car not working?
If you are getting very hot air all the time then the monovalve is seeing a ground at all times. Before anything else, check the connector on top of the monovalve. It is a small black plastic plug that could have been knocked off while you were changing the front shocks or air filter mounts.

Which is stronger a solder or a brazed joint?
Because of the higher temperatures a brazed joint is stronger than a soldered joint. In this process two metals are joined by melting them together. Of these three methods welding involves the hottest temperatures and welded joints are the strongest.
Can you use soft solder on cold water lines?
Never use solder with lead in an HVAC application. You could get away with it in drain lines, cold water fittings, and cold water lines that won’t experience large changes in pressure or temperature, but generally, you’ll want to use one that contains anywhere between 15 and 30 percent silver, known as a soft solder.
