left heated grip not working

Right one is super hot like it should be. Left hand grip isn't working at all. Any suggestions?

Thank you,

After much riding in the fall thinking I'd have to repair the heating wire inside mine, I found it disconnected.

Connectors should be hiding in the loom running along the right hand side tube, sort of just below the instruments. No locks on them connectors.

Troubleshooting this stuff can be frustrating sometimes - so you need to structure your steps and have a logical plan of attack:

1) Since one is working, we start with the assumption that the handlebar switch is OK and that the fuse is OK (only 1 fuse for both).

2) Each side (Left and right) has a simple 2 wires connectors that leads into a 4 wires WHITE PLASTIC connector behind the fork (see attached picture).

Unless you have very small hands, you will need to remove the front fairing and 1 or both side fairing to test the Voltage and Resistance at the connector.

3) With the ignition OFF, using an OhmMeter, compare the resistance of each wire pairs (Left and Right) - you should unplug each pair from the big White connector so that you are reading the resistance leading to the heating element only. BMW has not documented the value in OHMS, but for a working Heated-grip the resistance is fairly low. When the element is shorting or one of the wire broken between connector and Grips, teh resistance is very high or infinite. Compare the good working side resistance with the other side - they should be close when all is OK.

4) If you could not conclude a defective grip in the test above, you should now test for voltage at the WHITE connector for each side (each pair of wires). With Ignition ON and the Heated-grip switch at HIGH, you should read close to 12 volts for each side. If I remember (not 100% sure), when the heated-grip is set to LOW, you will get a lower voltage (approx 6 volts). Watch your time as you work with the Heated-grips ON as you may drain your battery - 5 min should be OK.

If you have found a problem in step 3 (most common cause) you might be able to repair by removing the rubber only and checking if one of the wires is cut inside the grip-tube. You can buy 1 side only from your BMW dealer, but it is not cheap (approx $110 each) - you get the "heated-tube + rubber + wires" as an assembly.

Another change....

Mine is a 2003 and doesn't have the 4 wire connector where the other 2s go in. Two 2 wires connectors coming out of the harness and 2 coming from the grips. May make checking out the voltage/Ohms easier in confined place if the OP's bike is like mine. But sure did make shrink sealing them easier,so they don't disconnect anymore.

Is the L/H grip damaged on the end indicating the possibility of damage to the wires within?

Yes I pulled the grip and the wires are cut.....I twisted them together for a quick test and still nothing.....looks like I'm gonna have to pull the fairings off again and do an ohms/voltage test.

I'll keep ya'll posted on the results.

Thank you,

I have a simple 12V light on the end of a pin tester which just checks for current. The black wire carries the current, with the light at full strength for high, and dimmed when on low. A very basic but effective way to check if there is power to the grip
