Why are the fans not blowing warm air when the heat is on on a 1999 Honda civic?
Sounds like your heater hose going to the heater core is stopped up some where along the way, Or your thermostat is broken. Otherwise if there is hot water getting to the core then it WILL blow warm air.
What else do you check after blocked hoses thermostat fans and radiator when your 1990 Honda Civic continues to overheat?
You have a 2000 Beetle you can drive it up to 35mph then it starts to overheat if you slow back down under 40 mph it cools back off what is the problem?
First thing that comes to my mind is that the air fans on the radiator are "reversed" this blowing instead of pulling the air in. To check it: Once the engine has warmed up and the fans are blowing, place your hand on the tail of the passenger side head light (where you would adjust the wind and elevation of your head light) Make sure you keep your hands AWAY from moving parts! If you…
Make sure all cooling fans around radiator and condenser are running with a/c on and engine running at operating temperature. If ok then most likely cause would be low coolant level or restricted( clogged) radiator. My sisters 91 did the same thing two years ago and it took a new radiator to fix it.
