Replaced clutch bearing on '95 LeSabre. Didn't have bearing seated all the way down on first try. Pulley rubbed on the coil where the connection is and broke it. Installed new coil and reassembled clutch. No voltage at either lead on wire harness when key is ''On'' and AC is turned. Assume blown fuse. Haynes Repair Manual says 15amp fuse,No.5 located in the "Relay Center" near the fire wall. Can't find it. Can you help?
Country: United StatesMake: BuickModel: LeSabre CustomEngine: 3.8
tested circuit with voltmeter with key on and AC calling for AIR. No voltage at either connection on plug.
Hi my name is XXXXX XXXXX let me see if I can find that for you...
It is located in the passenger side right kick panel area..so from he glove box that would be about 4 o'clock The fuse for the AC is # XXXXX - Hope that helps . Jim

Checked that fuse with ohmeter. It looks good and not blown. I forgot to add that after the pulley rubbing incident, the "Check Engine" light has been on. Sorry for forgetting that detail.I hope that helps. Thanks! Lloyd
If the check engine light is on we need to know what the code is. Could be related to why you have no power to the AC Clutch.. Try disconnecting the battery for about a minute and reconnect. If that does not work then this may take a bit of time to solve. Jim
I tried the battery disconnection. When I started the car the light was off momentarily but came back on.I'll take it to "Auto Zone"( about 20 miles) and have the code read. I don't have a code reader. Get back to you later. Thanks, Jim
OK.. I will check in from time to time.. There is relay in the fuse box that controls the ac clutch .. we can check that next for power switching ability.. If I am not here I can hand it over to someone else. Jim
Auto Zone did not detect any "trouble code". I was told a couple years ago that the earlier '95's did not have that good of a code system. While I was there I picked a new AC control relay. I will swap it with the one that is just below the 30 amp AC fuse on the firewall "MaxiFuse/Relay Center" and see what that does. There is one there that has the same description as the new one. I'll let you know.
Relay is OK. Rechecked continuity and diode from clutch connection up to near firewall. O.K. With key "on" and AC switch "on" found no voltage between relay and Powertrain Control Module(dk green wire with white stripe). It appears the problem may be in the PCM. What do you think?
In the relay socket there are 4 pins.. One is to the ac compressor, another is the power ready to be switched to the compressor, The last two are the control,, one is power with key on and the other is the signal from the PCM ... When the command is given the 'trip" wire should ground the relay and the contact should engage from power to compressor. They key is the switch signal from the computer. YES the dark green/white stripe should trip the relay.. You should have power on the pink wire and the dark green is the compressor. If you power the compressor wire will it engage?

Also be sure you freon level is up , it not the system will not turn the compressor on. Jim
Hi Jim, I won't have time to work on this now for a few days. But I'll get back to you for sure. Thanks for your help so far.
Not a problem I will check in from time to time.. Jim
Hi Jim, Got back sooner than I thought. Didn't get a chance to try your latest test yet, but I found out on our short trip( a couple hundred miles) that the " cruise control" is dead, too.That may help you narrow it down or it may not.Lloyd
Same circuit.. better check that fuse again... with a voltmeter..
Found blown fuse at 7R of that panel. Fuse 5 feeds the courtesy lights. I'll replace it later tomorrow and get back to you. Thanks!
Let me know.. ... Jim...
Back in business! Thanks, Jim for walking me through this. I'm sure I,ll be calling on you again. I hope the bonus is good enough.
Thank you... for letting me help you out.. Take care and enjoy the AC Jim
Having trouble with your website. Please forward this question to any qualified mechanic. 1993 Ford F-150. Just replaced leaky rear main seal and concentric slave cylinder and hydraulic line to clutch master cylinder. The clutch was fine, I just replaced it because I had all that stuff apart anyway. My question is when I bleed the new system, can I do it with my hand operated vacuum pump that I use for my brakes? Will that do a satisfactory job? Or is this more difficult than bleeding breaks?. Do I need to look for anything specific?. I've done alot of brakes.
You can use a hand operated vaccum pump Yes...If it does not work well..back bleed it or reverse bleed. Simply I got a small oil can from Harbor Freight, a clear plastic tube. Fill the can completly with brake fluid and pump till all the air is out of the line. Then I attached it to the bleeder valve on the slave and pumped it up till I say the master cylinder level rise with no bubbles left. There is video on You Tube showing this method. But the normal way should work fine. Let me know if you need more help... Jim
