What is wrong with heating in my 2001 Honda Odyssey?

Heating in my Honda doesn't work right. It blows almost cold air. I checked the hose that brings coolant to the heater core and hose the takes coolant out of heater core, and they are both hot. Does that mean that heater core is not good? Any suggestions? And how difficult is to replace it, because I can not afford to take it to the mechanic. I appreciate any suggestion!What is wrong with heating in my 2001 Honda Odyssey?you don't mention what model your Odyssey is. there are different possibilities depending on whether the car is an LX or an EX. the LX has manual air conditioning, the EX has semi-automatic.



if the car is an LX, first thing to do is to check the temperature knob. pull the knob off and see if the part of the knob that goes on the shaft is cracked or broken. more often than not the problem is that the knob is turning but the temperature control is not so you won't get any heat.



second thing to check is to see if the drain tube for the evaporator case is clogged. when the defrosters are run you actually run the air conditioner as a dehumidifier. when that happens condensation forms around the condensor. if the condensation (water) can't get out then the heater core gets submerged in water and the heat is transferred to the water rather than to the incoming air. you can usually get the drain tube cleaned out by having someone blow compressed air into the tube.



those are the two main causes if you have hot water in the hoses to the core.



I think you're going to find the temperature knob is broken.



if the car has semi-automatic air conditioning then the problem would be with a blend door actuator provided the drain tube is clear.



hope that helpsWhat is wrong with heating in my 2001 Honda Odyssey?Your core is ok. If not, it'd not be passing the hot water through. Check your fuses. The vanes that direct air through the heating system might not be working. If that doesn't turn up anything, find a heated parking lot and put your car in there for a few hours. That'd eliminate the any icing problem.
