    Random air conditioning blows hot air

    This oughta do it... Did you find debris on the Orifice Tube Screen? Delco started selling liquid line filters that were supposed to make flushing the system unnecessary. You really can't flush a cross flow Condenser (Evaporator for that matter) so replacing was a good move. Fords used to have...

    Overheating problems

    Seems to me too, that it's blown a head gasket... Unless maybe a coolant passage in the intake manifold...? Would a simple Compression Test indicate a problem, even which cylinder? Blow-Down Test even better, might hear the leak by listening to Intake or Exhaust. Or are these tests inadequate...

    Misfiring 454, 1990 non-HEI

    We need Zelda to get back with us and help clarify the situation. Maybe some pictures of the ignition components. Tomorrow will be a week that we've speculated but not heard back from Zelda.

    Rear disc brake problems 2010 Camry

    I don't know if there's a word screen to keep me from saying This Sucks, but this sucks. I've heard that compression fittings as used on copper tubing won't work on brake likes, but I've also read, here, I believe, that there are now compression fittings for steel lines AND they work with brake...

    Misfiring 454, 1990 non-HEI

    I wonder if it's terminology. Refresh my memory: Wasn't the name "HEI" first applied to the GM systems with the Electronics IN the Distributor AND the Coil in the Top of the CAP? If so, some would say a system with a traditional center contact in the Cap with a Coil Wire leading to a separate...

    Misfiring 454, 1990 non-HEI

    I'm still concerned about "Yellow as a Daffodil" about four sentences into the OP and again farther down in the thread. Even if it's not HEI, this IS electronic ignition. Shouldn't it be popping a hot blue or white spark? Just to me, in time or not, there should be a HOT spark.

    A/C not cooling at all.

    I think undercharged too. What you could do, is jumper the connector to the two wire Low Pressure Cut Off (LPCO) Switch on the Accumulator. Then see how low the low side goes. I'm guessing it'll go well below 19 and when it does that, look at the Degrees F scale on you blue gauge. It'll be so...

    Non working horn

    Picture might help. Here's a relay with a wired socket . By using a wired socket, you don't have to cut any wires, and you get a place to wire your UHB to.

    Non working horn

    Just for me, I don't see any risk of triggering an airbag deployment by installing a UHB unless you accidentally feed a signal into the airbag system. The risk I was thinking of, was that if you don't somehow disable the Horn Button Pad part of the Airbag when you connect the UHB, then you leave...

    Non working horn

    Before Airbags, many cars had two layers of metal under the vinyl horn pad in the center of the wheel. Layers had contact dimples stamped into them and the layers were kept apart by a sheet of foam with holes to let the dimples touch when we pressed on the pad. When the foam failed, the horn...

    Random air conditioning blows hot air

    Good for YOU! It's always good to do a thoughtful visual inspection. You probably don't know how that module controls the compressor. But you COULD tell that it was scorched and maybe badly enough to cause a problem. Great Catch!

    Non working horn

    I think the slip ring used for the horn back in The Day would make "noisy" contact that's not acceptable for modern electronics. Like airbag modules, steering wheel cruise and radio controls, so on and so fort. Clock Spring is a wiring harness, quiet till it wears out. And, allows all the...

    Shutting off during Hot weather

    I remember hearing about the platinum Ford plugs, with the platinum on only one side having to do with polarity or some such. I'd thought, a new set of Motorcraft replacement platinum plugs has it on both sides. True?

    Chain saw won't start hot

    Test it Cold and Hot with one of these Find a semi-dark place to do it. You can see the intensity of the spark. If it's a wide snappy blue streak cold, and narrow, quiet and yellow hot, weak coil. Breaking down from heat. Take the saw's spark plug out so it spins fast when you pull the starter...
