Chevy Equinox fuse bypass

[JerryofWV]

A friend of mine has a 2012 Chevy Equinox that he tows behind his mh. He installed a fuse bypass switch in it.

He was having problems with the ignition switch locking up when he tried to remove the key. It is still under warranty so he took it to a Chevy dealer to be fixed. After working on it three times they determined it was caused by his fuse bypass switch. They removed the switch and replaced the fuse and the ignition worked fine.

This didn't sound right to us shade tree mechanics so we plugged in the by pass switch and sure enough the ignition locked up again. We tested the by pass switch with an ohm meter and it is working fine.

Has anyone run into this before? Could it be caused by additional resistance in the circuit?

I have a 2010 Equinox with a switch installed and it works that way.
The guy who made the switch and wire told me about it. With the fuse removed from the circuit, the switch will not return to the locked position. That is why the key cannot be removed .

I've had my by-pass switch in my Terrain (2011) since new and have never had a problem with the ignition. However, the complexity of the current ECM equipped vehicle continues to baffle me. It would not surprise me in the slightest that adding this switch would have some other electronic/electrical reaction down the line. I can only add that mine seems to work just fine.
