Piston Slap: HVAC Heartaches Beset Panther Love?
I got a case of Panther Love and bought a nice 89 Town car. It’s a lower mileage (62k) girl, one that has been taken care of. I DD it.
I have been busy fixing everything that breaks on it. Previous owners just didn’t use her much, and so a wide variety of stuff just goes out. Window regulators. Alternator, battery, alignment, tires…… the list goes in and on. Every week something happens. That’s ok, and I expected as much. The engine, body, interior and tranny all seem good-superb.
It has of course an automatic temp control HVAC system, and and already I have been chasing numerous gremlins. Started with needing a new heater control valve as the floor setting never worked for the heater. That was an easy fix. But now it seems she has vacuum leaks under the dash or in places my good mechanics can’t find under the hood. Leaks that cause the system to do weird stuff, like sending all the air to the defroster under acceleration, and or switching from Heat to ac and back just for a moment. They have run all sorts of vacuum tests under the hood and can’t find the problem.
My questions is this: I have very good vintage car mechanics, but they charge 140/hour and it adds up quickly. And they are not HVAC specialists. They will gladly troubleshoot if I let them. Pull the dash and start poking around. That’s the next step.
Is there not a better way? Does an Ford (or any manufacturer) Vintage HVAC mechanic exist somewhere, someone who already knows the system? Seems to me that the experience curve might be mighty handy here. Something like a Lincoln doctor who is board certified in HVAC. That would be too cool. I can dream, no?
Or should I just stick with the guys I have and hope for the best while paying the man. I live in the Washington DC metro area. I am obviously not capable of doing this myself.
Forget Haptic Feedback - Jaguar Sees a Bright Future Ahead for Knobs
You don’t need to suffer from metathesiophobia to be uncomfortable with the wide variety of changes in the modern automotive industry.
Monostable shifters provide no firm detent when you’ve selected Drive, and often require a separate button for Park. Handbrakes that offer a level of modulation are quickly disappearing, replaced by electronic parking brakes. Touchscreens that require multiple menu steps — and seconds in which eyes are diverted from the road — are increasingly part and parcel of new car purchases at high and low price points.
Change is happening so fast and so often and in such unnecessary ways that there was much rejoicing when Honda revealed the 2018 Accord with both a volume and tuning knob, as if that was a bigger story than the dead V6, the discontinued coupe, and the seats being moved closer together to create an aura of space.
Fortunately, Jaguar will remain among the puritanical ranks. Jaguar will stick with the spartans. Jaguar will forego flashy transformations for the sake of primitive positioning. Jaguar’s climate controls will be operated via knobs for the foreseeable future. For old times’ sake.
Piston Slap: The Cadillac Hack
Geek alert! This one is tech-heavy!

Not a question, but it’s good to know that as long as there are cars there are people who will come up with hacks, no matter how complicated things get.
I have an 1992 Cadillac Seville and the blower motor fan disintegrated and jammed up the blower motor, which in turn shorted out the blower resistor. The squirrel cage disintegrated. I checked inside the blower housing to see if there was anything loose, but I could find nothing except pieces of the fan. All of this stuff was OE, no one has been in there since the car came from the factory. I’m sure someone at GM thought that saving a nickel on plastic was a good idea. Well, I bought a new motor/fan assembly and installed it. Wasn’t too bad, about $40. When I tried it, it was a no-go. Next thing I do is check the fuse (30 amp) it was fine. Then I checked the blower motor controller. It was blown. Crap! Apparently when the fan blew up, it jammed the motor, which then took out the motor controller. I’m thinking to myself:
“Nice engineering. The components on this circuit blow before the fuse does. WTF is the fuse for?”
