Piston Slap: HVAC Heartaches Beset Panther Love?

Peter writes:

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.

QOTD: Why Do You Hate Automatic Climate Control?

I recently posted a column about automatic locking, wherein I reached the following conclusion: automatic locking is the worst thing in the world. Worse than being buried alive. Worse than cutting off your own toes, one by one, for sport. Worse than a college student who won’t shut up about her MacBook Air.

As I was reading through the comments section of this column, I was delighted to find that most of you agreed with me: automatic locking, bad. Regular locking, good. But I also noticed something else: most of you don’t like automatic climate control. Poor little ol’ automatic climate control, just doing its best to make your automotive experience a little more temperate. Most of you hate it. Why is that?

Piston Slap: A Real Caddy, A Once in a Lifetime Deal…

Sajeev,

I recently picked up a 1969 Cadillac Sedan Deville. It was one of those once-in-a-lifetime deals you only hear about, like my uncles cousins sister is selling her deceased husbands garage queen for pennies on the dollar deal.

My problem is, the Automatic Climate Control (a $550 option!) does not work. The only settings that trigger any response are FOG and ICE. Even then, I can only hear the blower motor and just barely feel air from the floor vents. Where to begin the troubleshooting?

Thanks,
Kenzter

  • Kendahl A Tesla feature has been free, periodic, over-the-air, software updates that add new features or improve existing ones. Owners brag that their x-year-old car is better today, because of the updates, than it was brand new. Will Tesla start charging for these updates after a few years? Teslas hold their value very well. I suspect losing free updates will do serious damage to that.
  • BklynPete When I was a kid, the joke about Nissan choosing the name Datsun goes like this:Nissan execs were uncomfortable with the World War 2 connotations of their name in the North American market. Seeing how successful VW was over here, they went to VW's most-recent German ad agency. The Japanese told the Germans they needed a new name. The Germans agreed. They asked the Nissan execs when they wanted a review of potential names. The execs said two weeks. The German ad people said, "dat soon?"I will be crucified.

  • Arthur Dailey I believe that removing the screen from the instrument panel would greatly improve the looks of the interior. What of the Recaro seats? Any that I have tried have been too narrow across the back. Have they 'modified' them to fit North American drivers?
