    '95 Interior Heater Mystery Problem

    Heater not hot Is the air coming out the correct location (defrost, dash, or floor)? If the location is correct, the vacuum control is OK. If the vacuum source or controller is bad, the air flow defaults to defrost/floor and will not come out the dash vents. But the temperature door could still...

    Question: A low rubbing or squeaking sound..

    Noises from rear of Corvette My '95 made a few rearward groans and squeaks when I bought it with 60,000 miles. As the mileage approached 90,000, the groans got louder and more frequent especially when one back tire hit a bump. Every time I jacked the car up to look for the source, the noise...

    Cruise Problems

    No stalk response My wife bakes wonderful cakes; and delivers lots of them. We both love chocolate. And so do her customers. When the cruise control in her Blazer quit, I looked at everything. Nothing made it work. Everything seemed in good order. One day I noticed chocolate on my left index...

    No Acceleration

    Poor high rev performance Your symptoms sound like either a plugged fuel filter (but you've already replaced it) or a plugged cat. My experience is that a plugged fuel filter is steady bad performance but a plugged cat gives very sporadic performance. Sometimes great, sometimes poor at higher...

    HELP! Water Leak!

    Passenger side water Check your A/C condensate drain. I don't know where it is on your model but on most cars its on the bottom of the evaporator housing, visible on a lift behind the right front wheel and in front of the passenger floor pan. Sometimes a 1/4" hose, sometimes a 1" diameter...

    PROBLEMS WITH A 1990 5.7 AUTO

    Poor idle You likely have either a leaky PCV valve or EGR. The PCV valve is so cheap, just replace it. And check its hoses for brittle cracks; replace if you can get them. The EGR could be stuck or its control malfunctioned. I don't know how your year works; some have a vacuum solenoid that can...

    Oil change time

    Oil Change lifting Corvette I use staggered 2X10" boards; two about 6' long, the other about 3' long to get the front wheels high enough to roll onto ramps (one long board on bottom, one short board on top on each side). And the board ends are even at the ramp end. Block the rear wheels once on...

    94 LT1 engine rebuild or crate motor

    Crate motor I'd definitely go for the crate motor unless you have personal knowledge of a really good motor shop near your location. Google for 350 crate motor (perhaps add LT1 later) and you'll get a ton of hits. Don't recall LT1 prices but a 350 roller cam complete with HEI and carb goes for...

    C4 Corvette, best bang for the buck?

    Corvette shopping Welcome, you've found a great place for information and nice fellow owners. I too was looking for something a little different and when 59-1/2 arrived, I raided my IRA for a '95 Corvette. It was the Best purchase in lots of years of owning MG's, VW's, Healeys, pick-ups, 400+...

    Heater problem

    Inside air temp sensor The sensor (according to my '95 FSM) is located on top of the heater housing above the passenger side knee panel and bolster and it has two short electrical leads with a connector attached. To access it, remove the passenger kick panel then the bolster. Make sure to...

    Heater problem

    Outside temp The outside temp displayed was in error in both cars. That fooled the controller unless the control was set to 90. The inside sensor may be off. My son had a new Grand Prix with this problem. Dealer replaced the sensor but I don't know where it is. If you don't have a Helms, I'd be...

    Heater problem

    Hot air If you're getting truly 'hot' air with the setting at 90F, it's likely a failed sensor. In fact, that's the diagnostic technique. The outside one is in front of the right front tire, up near the radiator shroud and inside the wheel well. I don't know where the inside one is in a...

    Cleaning the Optispark??

    Slow start and dies often Welcome, this is a great place. And congrats on Corvette ownership. Your symptoms (especially having just taken your Corvette from storage) sound much more like a clogged fuel filter. Or slightly worse, a weak fuel pump. Doing a search for either using the tab above...

    PKE and Courtesy lights problem

    Courtesy Lights Today I observed the courtesy lights while parked in the bright sun. They did NOT illuminate after shutting off the key and opening the door. Tried it again later with my finger on the DIC light sensor and they illuminated. Looks like "it knows when they're needed."

    PKE and Courtesy lights problem

    PKE lack of sensitivity My '95 suffers the same fate as your Corvette. I've tried new batteries and had no success finding the 'original' type with the thin lip about the perimeter that fits the clip in the fob. The PKE works, just not at long distance. One thing I have noticed; if my cell...

    cooling fan diagnosis

    Cooling fan control It's a little more complicated than one simple 'AND' or 'OR' situation. If the speed goes over 40, the fan power cuts off. Regardless of other conditions. If the speed is under 40 and either the coolant temp is up 'OR' the A/C is on, then the fan is powered. To further...

    Camshaft replacement

    Cam replace Two kids in college? Feel for you; been there. How many miles on your Corvette? For the kind of $ and effort you're going to spend on a cam replacement, you can get some serious crate engine (tall block) NEW parts. In the old days (60's or thereabouts), there were a lot of cam...

    Vynil source

    Web site Definitely not. Small town upholstery shop that does top notch Camaro restoration work in between sofas and love seats. Nice guy, very reasonable and his work looks like factory original. He replaced some panels in my wife's Blazer that look totally stock. And he repaired my '69 Camaro...
