Honda 2003 CR-V Heater motor won't turn over when connected
The heater motor does run when directly connected to the battery. However, when connected normally it does not run. However, it will run sometimes and then sometimes it won't. Checked the first relay but that seemed to be fine. Can't find the second relay or switch to be causing the issue. Thanks!

you have some which are in the fuse box in the engine compartment with a fuse as well also some under the dash at the drivers side foot and i have seen some which are directly beside the heater box where the fan motor is located under the glove box passenger side but if the motor stopped working i would take a test light if you can use one and try the power and ground connections at the motor itself i see lots of motors burn out so it might not be a fuse or relay
not really, except unhook the battery. there are several things constantly running all the time. 'clock,computer, etc. eventially, the battery will drain. then again, your battery may be weak. an auto parts store will test it for free.
owner-reviewers on the Edmunds automotive website gave the CR-V a
reliability rating of 1 to 5 out of of 10, citing the vehicle's
expensive maintenance after passing 75,000 miles. On the AutoBeef
website, owners who reviewed the vehicle
reported a variety of AC and heater, electrical, engine, suspension and
transmission problems to be the main issues of the vehicle, with other
AC and Heater Problems
The most numerous issue faced by CR-V owners, air conditioning and
heater problems plague even low-mileage CR-Vs. Most owners report an
end blowing off the AC compressor, at an average of 76,900 miles.
Repairs cost an average of $2,660, but in some cases cost as much as
CR-V owners also cite electrical problems, prominently to locking and
window mechanisms and interior accessories. Reported everywhere from
45,000 miles to over 100,000 miles, owners say that the doors won't
unlock with the factory remote, the keys won't unlock the car, and that cigarette lighters and window buttons fail. Average repair cost per issue came out to $250.
Owners report irregular idle patterns, catalytic converter failure,
oxygen sensor failure and excessive engine oil use in CR-V engines.
Occurring under or around 100,000 miles, these problems average roughly
$2,500 to correct.
The two most common suspension problems are cracked ball joints and
misaligned struts, which can cause the vehicle to pull to one side.
Most problems occurred between 60,000 and 100,000 miles, and cost $300
or more on average to repair.
Complicated because there are two complete fan circuits, one for the air conditioning and one for the radiator. To test the fan motor itself disconnect the connector at the motor and use jumper wires to connect the motor directly to the battery. If it don't run-replace it, if the fan operates try the fuses located in the engine compartment or lower driver's side dash. Other than that seek professional help.
The heater not working.This problem is related to few possibilities
1) The thermostat can be faulty.
2) the heater blower motor resistor is faulty
3) The heater blower motor it self is faulty.
The The blower resistor is behind glove-box on plenum.Connect the 12 volt battery directly to the heater blower motor and see,if the motor runs then its faulty resistor or thermostat.but if no motor running then its faulty motor.The thermostat is located at the top front of the engine.For easy access follow the top radiator hose.The top radiator hose goes in engine .Take that hose out and thermostat will be seen inside.---------The thermostat and resistor are not very costly part.So you can directly replace them and see if its helping.First confirm motor is working,by directly by passing the blower motor to 12 volt battery.------------This will help.Thanks.Helpmech.
Check for a blown heater motor supply fuse,
Check operation of heater motor control relay,
Check operation of fan speed control switch,
Check heater motor speed control resistor pack (usually located in the heater ducting - in the air flow),
Check the heater motor runs if power directly applied to the motor- if not motor may be faulty.
If you have removed the blower motor, Connect it to a 12 volt power supply(your battery)with some jumper wires.It should turn fast, be careful when you connect it, have a good grip on it, it will jump just a little. If it dont run fast its junk. The other 2 things
1)The fan switch
2) The resistor that slows the fan at low speeds.
