Yep. Had the same problem on my 86. Changed the fan,sensor and relay.If you jumper the outer terminals on the relay connection you can tell if the fan works. If it does fine but the signal to 'throw' the relay from the ecm isn't working.Check with a test light for this signal.If ok replace relay.

Once again, seeing that I don't know a whole lot on the C4 Corvette I would ask this question in the C4 technical section on and get a dead on answer! Good luck!

Since there was no 1927 Corvette the answer would be NO.

A friend had the same problem with his 87 Corvette . His was the chip in the ignition key . Had to replace ignition switch and key , about 40 dollars for the parts .

it depends on what style of 81 corvette, But a doubt it would work.

Depending on the year it is 5 or 6 qts. LS1 style engines would be 6 qts.

It really depends on what corvette, if you ask about a corvette zr1 vs a viper, i think the corvette zr1 beats it by a mile,but if you ask about the corvette zo6 than i guess the viper would tie the corvette or beat it by a second.

The only nickel I can think of in a Corvette, would be in the engine bearing inserts.

have you tried turning the ouside dial on headlight switch that dims the gages bright or dull had a similar problem with 98 corvette no dash lights or hvac or running lights turned out to be multi function switch (headlights turnsignals)

I would search on ebay or craiglist for a used corvette at an affordable price.

check solenoid switch, starter cable will be hooked to it near battery

you cant does it click when you switch on ignition if not change it.

Try changing or checking the oil pressure switch next to distributor if it goes bad the engine will not fire or start. Motor (ECM) has to see at least 3 psi of oil pressure to start. And will also shut down if less than 3 psi.

Make sure the switch is plugged up correctly, and not up or down just A little,,,,,,,,,,,,,,, If correct, you got the wrong switch.

This would depend on the operating system, but in Windows XP, you go to Control Panel, Network Connections, double click on the NIC (Network Interface Card) in question. Click the Configure button, then click the Advanced tab. Be careful when changing speeds of the NIC. Most switches are set to Auto. Sometimes when you change the NIC properties you will not be able to communicate. Sometimes powering off the device will fix that, sometimes not. Also, you need to match duplex settings as well. 10mbs should be set to half duplex, 100mbs should be set to full duplex. The switch should be set as well. I have seen it that the switch was set to auto and changing the device would not work until the switch was set. Older printers were usual culprits.

You simply click it, and it should say something about changing it... so you click whatever comes up and it should lead you to a page with lots of different pictures. Just click the one you would like!

i am assuming you mean the switch for changing from one tank to the second tank if this is correct,either the switch on dash is faulty or the actual changeover valve on chassis rail is faulty

1979 The first Corvette was the 1953 so the silver anniversary would be the 1978

That doesn't make sense cause that would be the 31st year of the car.(corvette) They came into production in 1953. They did not make a corvette in 1983 so 1984 would be a 30th year. I've never heard of a 1984 anniversary edition tho.
