Question about 1997 Pontiac Firebird

1 Answer

1997 V6 3.8L Firebird - Low A/C

All of the fuses are good. Switched coolant fan (works great) relay with the A/C relay and everything the same so it's not the relays. Can't find the low pressure switch. There is a plug on the high side but it has 3 terminals and can't be jumped to activate the compressor. Anyone know anything else I should do before changing out the compressor because I have a feeling that it is not the problem?

If the compressor is not cycling on its own the system is either very low or empty, meaning there is a leak somewhere. The leak needs to be repairedd and the system vacuumed and recharged.

My honda civic radiator blowup what can be the fault


Hi!!
A radiator can blow up due to several reasons, the main and most frequent are:
  • A faulty Thermostat.
  • Low or leaking Coolant,
  • A defective or unplugged Coolant Temp. Sensor,
  • Defective Water Pump,
  • Faulty Radiator Fan Relay or blown Fuse.
  • Faulty Radiator Fan Motor or wiring,
  • Clogged Cooling System passage or Radiator.
  • Worn out (too soft) Radiator Hoses.
  • Wrong size Radiator Cap.
  • Dirty A/C Condenser Coil (the coil in front of the radiator)
Good Luck!!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

1997 camaro z28 fan isnt coming on, coolant is coming out of the radiator cap.. when i drive fast the car runs cool but when i drive slow it starts to overheat, what is my problem


the car is heated at low speed because less air flows at high speed and does not heat because the air flows more, check if the fan is turning on and check if you have good revolution,, check fuses, check the thermostat temperature, clean radiator use antifreeze coolant and finally check the pulley on the water pump with its setting correct ajustment. and finally if you work on the motor over time, verify that the ignition times are in place,

1997 firebird radiator fans are not coming on.


So if you tried another relay & they work, you need a new relay, right?

Fans wont come on


Does the temperature gauge on your dash work okay?

The coolant temperature sensor provides a signal to the PCM to tell it when to turn the fans on and if its a three wire coolant sensor it also feeds the signal to the gauge on your dash and if the gauge on your dash is not working, it could be a clear sign that the sensor is dead.

However, to start with the simple things, first check the fuses that power the fans, it will be a large fuse probably in the under the hood fuse box and maybe in the 30A range. Check the fan relays as well.
