No heat is coming out from my vents and AC isnt kicking on either what could be the problem or problems?

 

does the fan kick on and is there air blowing through the vents?

when you say the a/c isnt kicking on is it just not getting cold?

 

what he said

 

I'm having a similar problem. Mine only heats up once I have been driving it for about 10 min, and once I stop and idle the heat goes away. We just replaced the thermostat and that fixed nothing. A/C goes the same way, but warms up once I sit at idle.

 

I guess u checked fuses and relays already? Did u check if ur blower is good?

 

Not sure what you mean by blower. It can put out intense heat, but only after I've been driving it for 20 min or so.

 

this happens alot and i wish i knew why, ive always guessed at a air bubble i cant get to.

 

My car has good heat when i am driving down the highway but when i stop at a redlight it gets cooler, but warms right up when get moving again.

 

Your coolant sytem could be low on coolant. If there's just enough to fill the block, or the radiator, but not both, you could see inconsistency in the heat supply. If there's not enough coolant to fill the heater core, then you could see some fluctuation in the heat inside the car. My Chevy Blazer was doing that recently, and it was just low on coolant. After filling the overflow bottle, it seems to have corrected itself. It will take what it needs from that bottle. If it empties the bottle, fill it to the MAX line and try again. There is also a cable that pulls on a lever, actuated by the climate controls, on the coolant line coming from the block to the heater core (through the firewall), that controls coolant flow to it. make sure that cable is attached, and that the lever moves freely. If it's stuck, or works when it wants to, then hot coolant could be bypassing the heater core and you're blowing air through cold coolant through your vents, causing no heat.

 

The reason why it would run low on coolant could be a number of things. It could be a simple leak from a radiator hose (pin-hole leak on a hose, or loose hose clamp), or worst case scenario, a blown head gasket, blowing coolant out the exhaust. Or even overheating of the coolant, causing it to coagulate within the radiator, making it gunky and nasty. I've only seen the latter on GM vehicles using that DEX-COOL orange crap that might as well be freaking vodka for what it does. Honda coolant systems are usually pretty reliable.
