diy car air conditioning
I did the DIY Air Conditioning refrigerant change and may have messed it up.?
******************************************
When my AC is on I’ll hear a whining sound (i think) coming from where the compressor is located in the car. It comes on every 4 seconds and lasts briefly.
When it comes on I notice a very slight decrease in engine performance and I see a very slight dimming of my headlights.
If I turn the AC off during the whining sound it will immediately go away.
Any ideas?
FYI: 2001 BMW Z3
It didn’t take a full charge. Unfortunately, you need to bring it to a reputable repair shop.
It cycles on and off because there is just enough pressure in the system to allow it to run, but not enough to allow it to run continuously.
When you initially serviced your A/C it was most likely because it in longer worked. When you have a leak severe enough to allow all of the gas to leak out, you can get air into the system. When you charge your system, this air compresses and your system can’t take a full charge.
An A/C mechanic will put a vacuum pump on the system to remove all of the air and moisture from the system. Before he charges the system, he will find and repair the leak.
Did you know that your A/C system also requires a special lubricant to be added in the correct proportion to the coolant? Without this lubricant, you will burn up the A/C compressor. Sometimes, they just simply seize or other times they can glow a nice cherry red. Either one is expensive to repair.
