    No voltage at AC clutch wire

    1992 454 Replaced Measured Matched specs on 4 seasons pdf Same thing I dont think anything recently Whole thing was flushed first Vacuumed to damn near 30 and it held for a day or two. Doesn't really matter though because the compressor won't come on without a jump :sad:

    No voltage at AC clutch wire

    Oh also - unrelated but let me tell you this "reman" ac delco compressor is pretty noisy. I am almost positive I received a dud and it needs to go back.

    No voltage at AC clutch wire

    Sorry I should have been more clear. I can engage the clutch no problem with a wire from battery. I don't have a high pressure switch on the compressor it seems. I don't see any wire that would go to one. I tried jumping the low pressure switch on the dryer and that didn't work to engage...

    No voltage at AC clutch wire

    So I installed my reman AC Delco compressor and tried everything I could to get the clutch wire on the truck to give the compressor 12V. At no point will it do that. I even put 2 cans into the system...clutch won't engage. AC light on controller just flashes. What a headache. Is there a way...

    Blower Motor Resistor Did not Fix Fan

    Can anyone link me to a replacement dash switch for a 92? I suppose even if it is "working" by clicking the relays and changing the screen from LO MED HI it could still not be good enough to make the cut.

    Blower Motor Resistor Did not Fix Fan

    Mine is 1992. If its the dash switch would I still be able to hear the relays clicking? I can hear it click when I push medium and click when I push down to low. But the air will only blow on high. If there a way to replace that little rocker without replacing that whole digital HVAC display?

    Blower Motor Resistor Did not Fix Fan

    All, just put a blower motor resistor in there to fix my issue where my fan only works on High (i only have 3 speeds on and a digital dash). I checked the three relays on the blower motor housing and swapped them one by one with a known good relay and the same. I cannot get low and medium to...

    HVAC Won't Blow From Dash only Floor or Windshield

    My HVAC won't blow from the face outlets. Only floor or windshield. I have that digital HVAC with the recirc button. If I tell it blow from the face outlets it will close them off and you can hear the blower motor working hard without anywhere for the air to go. When you put it to floor or...

    AC compressor port on back left? Leaking from snap ring - what is it?

    Well I don't know if the switch works or not because it leaks around the perimeter. I think step one is evacuate the system, replace that o-ring if the switch doesn't break coming out, and then check for leaks. I would much rather run a metal slug and risk the system lol. I will try and...

    AC compressor port on back left? Leaking from snap ring - what is it?

    I do have a recirc button and noticed some replacement compressors have that switch port plugged off. If I understand you guys I can buy a replacement 2 wire switch and swap it in just to fix the leak. Wire it in to low pressure switch or I can just use the replacement switch as a plug and...

    AC compressor port on back left? Leaking from snap ring - what is it?

    I just realized that you said that is a switch. It did not have any wires attached to it. In my picture I see a loose looking connector with 2 wires going to it - does that look like the right connectors? I know it is leaking from around the switch as I checked but could also be leaking...

    AC compressor port on back left? Leaking from snap ring - what is it?

    Thanks folks. Well I guess I am going to bite the bullet and get a reman pump and a new dryer. Where is the orifice tube on these trucks - I should change that too. Thanks again.

    AC compressor port on back left? Leaking from snap ring - what is it?

    I found a leak on my compressor. This port off the back side of the compressor itself is slowly hissing. The compressor works and keeps the interior cool but that port leaks down to the point where the clutch won't lock anymore. Can I reseal what is there? It looks like a snap ring holding...

    Steering gear pitman seal

    I do see what you mean. I was hoping to leave it be and do the job real quick on the truck but it may be to my benefit to have the box on the bench where I can clean it real well and respray it afterward.

    Steering gear pitman seal

    Bringing back an old thread! About to do this job and was planning on doing it with the box still in the truck. Looks like I can remove those 4 bolts and pull the sector shaft right out, install new seals, and then bolt it all back together. Does this sound reasonable or does the box have to...

    Good R134 adapters

    I think I have some really crappy adapters on there and the system is empty. I will put some new schraders in and hoping to find an adapter that doesn't have its own schrader or if it does it allows me to remove the stock schrader. The schrader on schrader violence thats happening in my AC...

    Good R134 adapters

    My new to me truck needed AC charged. There are adapters on the R12 hoses to fit R134 adapters BUT the schraders are leaking. Can anyone recommend an adapter that works with the R12 valves in place or a kit that will work on the low side after I remove the stock schrader?

    454 Oil Cooler Delete

    I should have dug a little deeper before assuming all that oil on the lines was from the oil lines leaking. The leak was my high pressure fitting at the steering pump. Put a pan under it, removed the steering line, replaced the O-ring, refilled, and now we're dry. For now the oil cooler in...

    Factory tow mirrors?

    Color me surprised! So they stay since they are factory and I have DF2 on my Service Parts Identification. Next question is removal for paint. The 2 tone on mine needs the center section completely redone. The white is going fast. Are there welded nuts on the door skin or is it a nut and...

    Factory tow mirrors?

    My C2500 454 has tow mirrors. They are stainless and really nice. I can try to get a picture today. My question is: are they factory? There are nice plastic covers where the factory mirrors go. My friend says they are factory or at least dealer installed. I didn't think there was such a...
