What causes a VW Beetle compressor to not engage?

What causes a VW Beetle compressor to not engage?

As the terminals corrode, the fuse box develops excessive resistance and heat that can burn up the plastic frame, also resulting in a burned compressor clutch fuse, wire or simply a compressor clutch won’t engage condition. The problem fuse bracket can be found on all 2001-05 VW Beetle vehicles

How much does it cost to fix a VW AC compressor?

However, we found that trick and for only $25 we can fix it. We have seen those go bad on VW Jetta, Vw golf, VW PASSAT, VW EOS, VW TOUAREG and more. You do not have to replace the a/c compressor, 90% of the time is this solenoid. In some cases it might be the a/c compressor but not very often. This is NOT a sponsored video.

What should the voltage drop be on a VW Beetle?

If you see any signs of corrosion, heat distortion, insulation melting or fuse damage, replace the entire fuse bracket. Conduct a voltage drop test. Voltage drop under load should be almost 0-volts. A voltage drop above 0.30-volts is a sign of excessive resistance. In that case, replace the fuse box.

Why does my VW Beetle not charge properly?

If you fall for that, you’ll replace the alternator and it still won’t charge properly. The high amperage power runs through the fuse bracket before going to the positive battery terminal. If the fuse bracket shows signs of corrosion, heat distortion or insulation melting, that heat can also burn the fuse terminals.

Why is the clutch on my VW Beetle not working?

Shops are finding the root problem for a VW Beetle compressor clutch won’t engage may be caused by a fuse box corrosion issue, not a bad compressor clutch or low refrigerant issues as most people suspect (VW calls this a fuse bracket).

What to do if your a / C compressor won’t turn on?

Have someone watching the A/C compressor while you start the truck and turn the A/C on. If the compressor cycles on, turn it off. You now just narrowed it down to either low refrigerant or a bad pressure switch. Keep it Professional Grade. Use Genuine GM Parts Cut your fingernails. That’s not me. And spell your name right.

What’s the duty cycle on a Volkswagen a / C compressor?

3. Verify an approximate 70% duty cycle from the A/C pressure sensor at pin T14/2 (white) with the ignition on and the compressor not running (duty cycle will decrease as the high-side pressure increases).

Where is the blower motor on a VW Beetle?

Carefully pry off the lower footwell trim panel, and find the blower motor on the lower right-hand side. It is black and cylindrical with a white fan attached. Unscrew the four screws holding it in place. Make sure the pilot lights inside the vehicle are working and the graphics display is lit.

Where is the fuse box on a VW Beetle?

The fuse box sits under the hood above the battery and can develop corrosion from road salt spray and battery fumes. As the terminals corrode, the fuse box develops excessive resistance and heat that can burn up the plastic frame, also resulting in a burned compressor clutch fuse, wire or simply a compressor clutch won’t engage condition.

Why does my air conditioner clutch not work?

Repair Topics > Air Conditioning Symptoms… > VW Beetle AC Compressor… Shops are finding the root problem for a VW Beetle compressor clutch won’t engage may be caused by a fuse box corrosion issue, not a bad compressor clutch or low refrigerant issues as most people suspect (VW calls this a fuse bracket).

What to do if your a / C compressor is not working?

Using a fused 12-volt jumper, apply power to pin T14/10 (green/black). The compressor clutch should engage. If the compressor does not engage, check for a wiring harness open circuit or loss of ground at the compressor. Reconnect the 14-pin connector.

Why is there no power to the a / C compressor?

Potential Causes: A/C Compressor, A/C Pressure Sensor F129, A/C Switch, Ambient Temperature Switch F38, Battery Auxiliary Fuse Box, Fan Control Module J293 (and Wiring), Fuse or Lost Throttle Basic Settings Test the Fan Control (FCM) module inputs as follows: 1.

What causes a / C to work on a VW?

Note: Pin T14/3 will be grounded by the ECM if the throttle basic settings are lost. Raising the engine rpm over 2,500 will cause the ECM to allow A/C operation if this is the case. If a ground condition exists on pin 3, perform a throttle basic setting procedure and recheck for correct voltage.

Where are the fuses on a new beetle?

Location Volkswagen New Beetle – fuse box diagram – location Fuses -S162-, -S163-, -S164-, -S176-, -S177-, -S178-, -S179-, -S180- on fuse holder/battery Fuses -S43-, -S111-, -S130-, -S144-, -S283-, -S329-, -S337-, -S338-, on the 13 position additional relay carrier above the relay plate Fuses (S) in fuse holder, left dash panel

Why is my AC compressor not coming on?

Compressor not coming on As the pressure switches control the on/off function of the AC compressor, a switch failure can prevent the AC compressor from functioning at all. The compressor is what pumps refrigerant through the entire system. If it is not functioning, then the system can not operate, and will be unable to produce cold air.
