    I like "REDUBMDANT!" for redundant.

    Was just pointing out back then with any vehicle could get a full service manual with free shipping from a coupon in the rear of your owners manual for five bucks. And they had complete fold out circuit diagrams in full color and even gave specifications on various sensors so no doubt if they...

    Question on o2 sensors

    Ya, upsteam front downsteam rear, upstream right downsteam left, four different O2 sensors. Use to be just one, they are extremely slow in responding, takes a good microcontroller to iron things out. Big job is to keep the stoichiometric ratio constant. Too rich, hydrocarbons in the air, too...

    2004 Lincoln Town Car water leak on driver's floor

    Daily driver in the northern salt belt area won't even last 7-8 years before it turns into a pile of rust, looks like yours lasted 16 years, must be in a salt free area. What happen with this vehicle when you go through a car wash, can you see the water pouring it.

    03 Saturn lw200, can't restore power to AC/heater controls

    Blown fuses are a nightmare generally rated at 150-200% of the normal current draw, something is shorting out. Could a cable close to a sharp metal edge being grounded or more typical with a 17 old MVAC blower motor, brushes are near warned out or the bronze bushings are dryer than a dessert...

    PO101 Mass air flow.

    Another problem with these things, the PCM requires a start voltage of at least 8.5 volts so that its microcontroller gets a proper POR or power on reset. If not the program counter is not reset to zero randomly reads code that also was not properly reset. Another cause of this lower voltage...

    R134a port caps

    Would something like this work that would screw unto the R-134a caps making sure nothing inside will open the ports. Could use convention R12 steel caps or just seal the top of these off...

    R134a port caps

    Back then, nobody in the US heard of the metric system of units and some weird thread sizes were used, but spark plugs of today are more standard metric sizes. Would have to dig back to my notes to give you those weird sizes. But even today in particular for spark plug and lug nuts hex sizes...

    Moth in Engine!

    We have some here in the cliffs of LaCrosse and Winona, but they are slow and stupid. Not like those sidewinders out west or down south that can crawl if this is the correct word faster than a man can run. More predominate in our locate is a pine snake, not poisonous, but bite will hurt...

    Moth in Engine!

    Down south a buddy of mine opened his hood to find a rattle snake coil up on his air cleaner. Just looking for a warmer spot to spend the night. Was carefully opening my hood after that.

    ac blows cold then hot

    A company I was working for 50 years ago wanted to make an engine compression tester with screw in fittings as opposed to using a neoprene cone. Those threads were non-standard like these R-134a threads, we had to pay a small fortune to have dies made for our automatic screw machines. So Bill...

    ac blows cold then hot

    I was tricked Bill, should report the seller, but a closer looked revealed aluminum coated plastic. In doing another search,many are having problems with R-134a ports leaking, even my quick connect air hose couplers leak like crazy. Who is to blame, EPA and SAE, but the EPA is super critical...

    Have a 5,000 page shop manual for our 2017 Hyundai Elantra Limited in pfd format, using Adobe Acrobat Pro that has a far superior search engine then the reader version, but somehow lacks an index. The owners manual is over 700 pages long with a rather long section on DMV driving information...

    ac blows cold then hot

    Did find chrome plated brass with neoprene seal inside for my tire valves, these would fit on an R-12 system, hexed shape so could use a wrench. One port is an non-standard Acme thread of 1/2"-18, standard 1/2" threads are either 13 or 20 TPI Special tooling is required, could turn them on a...

    ac blows cold then hot

    Mechanical high pressure switches were common back then if you don't mine back then. Today, using a thermistor plugged into a BCM to kill the compressor if the high pressure, actually a proportional temperature sensor fed into a BCM to cut off the compressor clutch. Latest compressors are...
