ok, so it almost winter and my heat went out. well not my heat but everything. i checked the underdash fuse and it was good. i pulled the blower motor out and put power to it , it works. i changed out the resistor pack still nothing. nothing will turn on. any clue? help me out im cold!!!

 

check your coolant...if you are low on coolant your heat wont work...do you have a coolant leak or maybe a leaky head gasket?

 

thermostat switch, i have the same problem on my car..im to lazy to go fix it but im 99% sure its the switch

 

check your climate control. I'm going thru the exact same problem, changed the resistor,fuse and checked the blower motor and relay, but I'm pretty sure my climate control is loose or broken, it works once in a blue moon when I pound on my dash! just kinda figured it out today hah. good luck

 

thanks, its not that i dont have heat. it does not blow anything out, thats why i thought it was the blower motor. and my climate control lights went out. still have to check the relay. help!!!!

 

check the blower motor switch for power and ground............

yea in my daily it is doin the same thing, doesn't blow out anything. sucks, i have to layer up to go anywhere, but hopefully can have it figured out this weekend. fingers crossed

 

the switch that says............... off 1-2-3-4

 

UGH it's your thermostat. It doesn't work properly. Almost always when a thermostat fails, it fails open, meaning it always stays open, meaning as soon as you start the car your coolant is automatically flowing through your motor, thus not allowing it to heat up, which gives you heat! Just my 2 cents..

if you put power to the blower and it works the problem lies somewhere in between the battery, switch, relay or wiring

 

If you have no heat, you're obviously not hitting VTAK...

It's so logical.

You fail

 

my switch went out a while back... melted the in side of the switch... went to honda delership got a new i think it was like 15 bucks?

dose your switch move to every number and stop? or dose it go from off to 1 2 3 4 with no bump/stop?
