Kind of reminds me of my 95 Civic with intermittent compressor operation where I ended up removing the control panel assy. and soldered all connections at the pc mounted switches. That fixed the problem plus fixed an intermittent problem with the vent mode switch not allowing the air door to direct flow to the vent outlets.

I am a retired equipment mechanic and saw many clutch coil failures on Sanden compressors and was giving him my thoughts on that, but there may be other problems as well I see.

Myself, if the clutch coil was available on its own, I would have only replaced that. Compressors get replaced way sooner than they should. Great video Ivan. I had a compressor than was just 8 months old and the coil burned up during summer heat. It still worked at lower RPM but didn't have enough grip to hold the pulley tight enough above 2,000 RPM. Couldn't source a new coil so I have a good compressor and cannot repair it without buying a complete new compressor with the clutch coil. Sad.

@Ray Milligan Might cause a balance problem? Our ultimate solution was a new compressor assy (UAC brand), dryer and recharge the system. Older car yes, not a junker.
@Garth20114 жыл бұрын
@@anonymic79 The coil burned up in one area, the paint was bubbled etc. Didn't check the shim as the gap appeared within spec however, on this vehicle, the pump had to be removed in order to get the coil off so, it was going to be a job that involved evac/recharge regardless and due to parts and hassle, went for the $190 UAC compressor. As long as the new coil doesn't fail before the compressor does, we have a spare coil that can be put on the old compressor if that time comes. My guess is, during 115 degree weather, there was voltage drop that may have occurred just enough to allow the coil to heat up ?
@billwasylenko15994 жыл бұрын
A lot of the time you have to remove the compressor to replace the clutch and or coil. By the time you buy the clutch and the coil you’ve spent the same if not more on those 2 parts than the cost of the whole compressor. For the customer’s car compressor replacement makes sense. On the other hand if it were my own car and it has the original denso brand compressor or other oem than yes I might put a coil and a clutch.
@topher863410 ай бұрын
Most of the time a clutch, hub and coil kit isn't much cheaper than a whole new, not reman compressor. And with the high failure rate of Sanden compressors, it's not a bad idea to replace the whole unit along with a new drier.

Must be a TXV system - back in the old days (lol), constant running would've starved the new compressor of oil pretty quick! Oil that's below freezing doesn't like to move very well. Years ago I had a failed LPCO switch smoke the R4 pancake in my '94 K1500. She got REAL noisy after that! Was nice to briefly have sub-freezing vent temps that one day, HAHAHA! Then when I attempted to remove a line to the condenser (replaced in case metal was in it), the line twisted off with the nut. Can O'worms that one was! $500 later, she was back cooling the cab again. This was the opposite of a "NPR" fix - this was a "MPR" (MANY parts required) fix! 😁 Interesting voltage readings there!

@@PineHollowAutoDiagnostics Honda should examine the part with a postage paid sticker so they can engineer the fix. I'm amazed at the cheap crap parts coming from OEM which isn't supposed to occur.

Experience comes into play at that point.
@averyalexander23034 жыл бұрын
@@Garth2011 I agree with you, but I think a lot of manufacturers probably have stricter quality control standards for their OEM parts than their aftermarket parts. For mission critical or difficult to change parts, I tend to go with OEM parts where possible. One example of why is I bought a FelPro rear main seal for my Civic from a local parts store to replace a leaking one while I was changing the transmission and the replacement seal leaked, so I had to take the motor out to replace the seal again. Upon further inspection, the reason the seal leaked is because the round metal spring on the back of the seal that holds it tight around the crankshaft was missing. I guess I should have visually inspected the seal before I installed it, but it should not have left the factory with a missing part either. I replaced the seal with an OEM Honda seal over a year ago and still have no leaks to this day.
