Well to begin, I have a 93 A/T RS. Has less than 90k miles on it and has had many things replaced (Radiator, distributor, transmission, VSS, timing belt, water pump) and gets all scheduled maintenance done.
Now to the problem…
I went to start the car up but it wouldn’t start until I cranked it a few times. It bogged and hesitated but I gave it enough gas to keep it running so that I could move it onto the driveway from out of the street. I then smelled something burning…I popped the hood and noticed there was a wire with a black plastic piece at the end of it that had melted through from hitting the belt on the compressor. Through the melted plastic I can see copper that looks to have been disfigured. This wire is screwed onto the compressor in place and when I went to trace where it plugged into, I found nothing. The end of the wire was just sorta hanging out. Can anyone tell me what this wire is/does/controls? And would it affect my car bogging down to the point where it seems it’ll stall after I snap the thottle?
r u talking the a/c compressor? if so there is only 1 wire coming from it that connects to ur a/c fan and i dont see that having an effect on ur idle… is ur CEL on?
Nope cel is off. And the wire is screwed onto the a/c compressor, not sure if it’s actually coming from it since 1 end looks to be melted and broken off and the other end was just hanging.
it shoudlnt have anything to do with the cars running as far as i know… ac work fine? i had a friend blow his main vac line and it did the same thing. but his wouldnt start again. it made a noise like it blew the motor… it was just a backfire through the intake making a soundlike a blown motor… turned out to be a vaccum line… did u check for leaks?
Not sure what the wire is, but if you could smell something burning it indicates a short, as does the burnt wire, and a short in the electrical system could definitely effect the engines ability to run properly.
When you say the wire is screwed into the compressor, what exactly do you mean, where on the compressor is it screwed in, there should only be two wires going to the compressor, a black, [ground] and a red, [12V+ from compressor clutch relay] and they are in a plug and plugged into the compressors coil at the front, [pulley end] of the compressor.
Can you take a pix of the wire and where it is screwed into the compressor, can you tell what color the wire is?:hmm:94
Alright, now that it’s daylight I can see what’s going on. Thanks to your help, I see it’s the wire from the relay and the ground wire that are screwed there. I disconnected the power wire form the relay since the ground side is melted through at the plastic end. This end I guess goes into the compressor coil, but I can’t see where that is. Any idea how much this wire costs? And are there any adverse effects to driving it like this? A/C still blows cold, and with the A/C running I can snap the throttle and the RPMs will go down just to idle. Without the A/C running, after I snap the throttle, the RPM’s go down to the point where it feel it’ll stall out.
If the A/C compressor clutch relay is unplugged or the lead to the compressor clutch is unplugged then clutch can not engage and your A/C can’t work, check and see if the compressor clutch is actually turning, you can hear it engage, [click] when you turn on the A/C switch, and the clutch hub will start spinning, if it does that, you have not disconnected the A/C clutch relay or unplugged the power lead.
The power/ground leads plug into the compressor clutch coil, right behind the pulley, the clutch is right in front of the pulley, some Honda compressors have the pressure switch mounted right into the compressor, normally towards the back close to the liquid and vapour lines, [tubing], in which case the 12V+ lead from the relay goes through the pressure switch before it is plugged into the clutch coil, however they are grounded through the compressor case and only one lead, [12V+] is run to the compressor.:whisper:94
