i have a 1995 lt1 camaro and i have changed the temp sending unit and all fan control fuses and my heater also does not get hot even if the car is at a temp of 220 degrees why are my fans not kicking on and why is my heater not getting hot . if i set at a red light the car will beging to over heat and i have to turn the airconditioner on to make the fans kick on . someone please help

not sure on the heater problem, but for your fans it kind of sounds like you've used the wrong sending unit. is your sending unit supposed to be used with a gauge? if so, it will act as a resistor and only supply so much power to a gauge, to indicate temp. what you need is a temp sensor that turns on at a certain temperature. then when the engine gets hot the unit will switch and send power to the fans. hope this helps.

Sounds like your low on coolant!!

Sounds like you have a bad thermostat.

Have you checked your fan relays. Some cars use a 2 speed fan. The computer will call for low speed first, then if the car continues to over-heat the computer will call for the hi speed. The A/C always gets hi speed. Check for 2 fan relays under the hood.
