I may never figure out why so few of them work but, in less than 90-days, I finally understand why so few people bother to repair them.

If Wyoming was home and I was snowed in for a few months it might be a project. Otherwise, I have never encountered a driver's car quite like an air-cooled 911.

So few of them work because the control modules are 25+ years old. The solder joints on the PCB fail eventually. Whether or not one repairs it depends on how they use the car. If they do a lot of cruising on freeways, CC is a nice thing to have.

Mister Moo

It was more of a rhetorical observation but, yes, I guess improved circuit ruggedizing and softer suspensions add up over the decades. CC on the '91 MB, similar/same module I think,now 600,000-miles old, remains flawless thank heaven. The 3-ton rock driven by an aging diesel doesn't have exciting pedal action on the highway.

Perhaps Carrera-novelty wears off sooner or later but, so far, I like my right foot on the pedal. I haven't had a ride without cruise since the '80s - even the last four motorcycles have had cruise - but I'm not missing it (yet).

I never even tried to see if mine works! I will out of courioisity now. lol
Othen than that, I have no use for it.

I feel that the aircooled 911 is in it's element on fast jaunts of about 2-3 hours. It's an exhilirating shot over the mountains or to the coast. Having the cc set at 80 mph or so is a nice feature.

In the 3 months I've had my 911, I haven't had it successfully running long enough at any one time to even need the CC. Fifteen miles seems to be its limit before something breaks.

Maybe one day.

Mister Moo

One thing at a time. Work the plan.

That sucks, and is definitely not the norm. We can probably help with a lot of the diagnosis on the forum.

It's mostly minor junk: fuses, lights, etc; the one big exception so far being the clutch helper spring, where this forum WAS a big help.

I want to drive it this weekend, but after my last flatbed ride, I'm a wee bit leary. Oh, what the heck!

Well, I'm with those of you who never use it. I've only had my 911 for 12 years or so. Never once turned it on. For that matter, I haven't done so in any of my other cars either.

The typical cruise control (CC) problems are:

1. The CC won't engage;
a. bad brake switch
b. bad clutch switch
c. no power or bad column switch
d. actuator bad or no vacuum
e. actuator cable disconnected
f. no speedo input
g, bad CC

2. The CC engages but won't hold the speed;
a. bad CC
b. bad actuator or vacuum leak

3. The car surges (speed fluctuates);
a. bad CC
b. bad speedo signal
c. actuator cable loose

Mine works fine, and I use it on the 401 (boring divided highway in Ontario) to keep from getting busted for creeping above the ticket threshold. Otherwise I tend to settle in at about 140 Km/Hr. Truth be told, it's the fastest way to turn the funest (if that's a word) car in the world, into a mind numbing grocery getter.

CC allows you to drive for hour after hour just a tad bit ABOVE the speed limit CONSISTENTLY without attracting attention...

Used my CC alot on my drive home from Miami to Maine. It is nice on a long trip.
