Re: A/C won't work 03 Acura RSX
General Troubleshooting Information
How to Retrieve a DTC
The Climate Control Unit has a self-diagnosis function. To run the self-diagnosis function, do the following:
1. Turn the ignition switch OFF.
2. Tu rn the fan switch OFF, the temperature control dial to MaxCool (60.F or 18.C), and the mode control dial to Vent.
3, Turn the ignition switch ON (ll),then press and hold the recirculation control switch. Within lO seconds while holding the switch down, press the rear window defogger switch five times. The recirculation indicator blinks two times and the A/C indicator comes on, then the self-diagnosis will begin. About 15 seconds later, the self diagnosis will finish and the Ay'C indicator goes off. lf there is any problem in the system after finished self diagnosis, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 1 through 13. When problems in the evaporator temperature sensor circuit are detected (codes 14 and t5), the A/C indicator will blink the DTC. lf no DTCs are found. the indicator will not blink.
Resetting the Self-diagnosis Function
Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the self-diagnosis function again to make sureA/C won't work 03 Acura RSX - eb2936e.jpg are no other malfunctions.

under-hood fuse block. fuse 16--20amp, that voltage goes to load/switch side of fuel pump relay. There is also voltage that goes to coil/control side of relay, that is 2 amp fuse, interior fuse box comes from pcm relay.
There is also a bump switch that you might need to check. Your owners manual should have this info.
detach the whole fuse junction box and check the back of it; the may be allose cable or sth... else check if the circutry passes through any reed relay int htis case it may be blown or stuck; detach it give it some gentle bumps if problem persists get a new one with exactly the same specs.
If you mean the inertia switch that shuts off fuel in the event of a crash, that is a Ford only part-no others have them.
Does your fuel pump turn on for 2 seconds, with key on, not start? If no, check the ECM-B fuse (20 amp) in the power distribution box by left (driver's) fender. This fuse sends power to the fuel pump relay, also in the distribution box.
To verify a bad fuel pump, check for power on the pump wire at the fuel tank connector with the engine cranking over. It is a gray wire. It should also have that 2 second signal with key on. But with engine cranking over, it should be a steady power signal. If power is on the wire, before condemning the pump, check the fuel pump ground. If ground is good, the pump will have to be replaced.
If pump is working and you have pressure up to the injectors, you will need to check the injector circuit. Post back with what you find.
yes it could be just a wiring, fuse or relay problem. Most common is the starter relay in the fuse box, or a bad ground somewhere. If the relays, wires, grounds are all good, might just be the starer solenoid that is faulty, or the starter motor itself. In both cases nowadays, you will need to remove the starter to test either the solenoid or motor. Also might be a good idea to check if voltage gets the the relay in the fuse box when you turn the key, as contacts in ignition switch can be faulty. Just remove starter relay in fuse block and check the right pins with a voltmeter while a friend turns the key in the ignition. Hope this helps :)
First, check with the key on to see if you have power to the pump, if no power then we'll look elsewhere, Some solutions could be a faulty pump Or Inertia switch, but that does not match with having to tap the fuse box to start it, Also, remove the fuel pump relay and with the key on test for power to the relay, this can be done with a simple test light.
