actually no I would not since it could be lots of things making this happen-------bendix and horn work opposite. One takes air to lock the other takes air to unlock. With that being said you might need to switch binary/trianry switches after you switched them to be the same.
I do away with the ones that are locked in at startup until the truck builds air-------------we are just careful to make sure the AC high pressure switches function in these trucks since high pressure under the right conditions can take place before enough air is built to get things locked up
so they put in a high pressure to engage the fan
but with no air pressure in the truck if they would just put a high pressure switch to stop the compressor
the rad fan not having air would then have a "safety " |
