20 Most Recent 1998 Volvo C70 Questions & Answers

well i would think just by what your saying about jiggling the key that its the ignition switch but lets not jump to conclusions,
start by getting a voltage meter, can find them cheap and they will help you tons, check the voltage of the battery. off it should be 12.5 minimum running should be 13-15 under a load (load meaning ac on full headlights on bright etc) if its lower than that have a local auto parts place check your charging system and or battery, , also clean and check the battery terminals a few minutes will save you a ton of headache down the line even if its a bad switch.
then move onto the diagnostic for the switch, for that you need to feel compitant enough to get the steering column cover off so you can access the wires to the switch, once you get to that point wiggle the wires while attempting to start it, maybe one of the solder points is bad. another item to keep in mind that might be bad if its standard is the neutral safety switch under the clutch pedal
also once you get to the wires for the ign switch, find a way to diagnose it, i would advise you on that but every car is different on wire colors and the way the switch works so look for a ignition switch diagnostic aid from a dealer or from online for the exact year make and model and go from there,
if you cant find one by the above means i might be able to find the information on that.
good luck!
also if you replace the switch you may need to reprogram the key if it has a chip inside of it just keep that in mind if it wont do anything after you swap it,. a good reputable locksmith should have a key re-programmer and should be able to tell you if its chipped just by the appearance of the key.

I don't work on these, but , remove the rear seat, bolted in. or drill out the lock until it can be turned. Being a 98, you will still have to climb in it and release the latch by hand. And it is most likely covered. Break the cover off.

HI. This will, generally, be the result of the cooling fan switch.

The cooling fan switch on most electric fans monitors coolant temperature signals from the engine control computer. When the engine is cool, the switch opens to keep the fan from spinning. When the engine is warm, the switch closes, thus, turning the fan on for cooling.

I would advise to Inspect the cooling fans(thermal switch),wires and connections. Cooling fan switch problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the switch itself. If the wires or connections are bad, replace them. If you think the switch is defective, it should be tested.

The electric fan cooling switch, or thermal switch, can be tested by placing the element in a bucket of water. Heat the water to approximately 207°-216°F (97°-102°C) and connect the switch leads to an ohmmeter(make sure to keep the switch leads out of the water). The switch should have no continuity until the temperature reaches this level. Let the water cool off below 207°F (97°C) and the switch should lose continuity. If the switch has no continuity at any temperature, replace it.

NOTE_The thermal switch is located on the top of the radiator, usually on the passenger side.

most likely cause is water intrusion through the cabin filter

pull the filter
if wet then you need to find something that diverts water away
many OEM's have had this problem but nothing on file for this vehicle

That would be a blown head gasket. Do not drive your vehicle like this or you can cause serious damage to the engine.
