Were are the switches located and how can I test a relay.

 

99% its the relay. My buddy had the same issue with his at strangely near the same miles. You can ohm a relay out with a volt meter.

 

I'm thinking it's a relay to but not sure what one since there is like 4 a/c ones

 

Best thing to do is ohm them out. Grab a volt meter and pull em out and go to town

 

Had a lot of 240s in my car days and always had electrical issues so I know these can suck to figure out

 

I can tell buy your sr20 name . Anyways how do I ohm them out. Sorry new to this I know how to test everything but a damn relay. Might just take it to mitsu and pay them 75 bucks to look over everything

 

any info as to what happened? im having the same issue with my car but its an 03
i checked all fuses swapped out the resistor and tested the blower motor

 

No clue man I have checked everything too with no results yet. Looks like I'm going to take it to the dealer.

 

lol really?? barely? i think im going to do the same..

idk if its coincidence or not but my door locks arent working anymore.. the remote unlock/lock nor when you put the key in the door do they all unlock when you turn it twice


is there anything else that i should be checking for? besides the blower motor and resistor

i also check all the fuses in the engine bay and interior all seem good

im serious fed up with this car

 

Check the main fusible link for your car. I had the same issues I blew mine somehow and my door locks, mirrors and trunk didn't work. I found the problem to be this. This main link dose control the a/c too thing is mine still dose not work

 

time to start pin testing for power/ground

 

How do I go about that man? Never tested a relay before this Is new to me.

 

Ok, here's a diagram of the area you need to be looking at. As you can see, the relay for the blower system is actually integrated into the car's ETACS ECU, so you're unable to test it like a normal relay. You're going to have to check for power and ground at the individual connectors and narrow down which part of your system is actually at fault.

 

What if it's the ETACS ECU??

 

Buy a portable fan! lol
