Hello, my name is ***** ***** I'm here to help get your problem solved.
If the 15 amp fuse in location 18 of fuse box still blows with the ignition coil relay removed this means the fuse box has internally shorted out and needs to be replaced. Let me know if you have questions, thanks.
Here is a picture, let me know if you have questions. Thanks.
This means one of your coils have probably failed, disconnect each coil one at a time to see one allows coil to stop blowing when unplugged then replace that coil.
I'm happy to help, let me know if there is anything else I can do. Thanks again and please do not forget to rate answer.
You can continue replying even after paying but we can try to get that figured out now. Why did you jump switch to begin with? Does fuse still blow or did it only the 1 time?
Have you connected a gauge to make sure AC is properly charged?
Have you checked codes in HVAC?
Here are instructions, let me know.
Check them and let me know what they are, thanks.
I'd go ahead and replace the pressure sensor, after that it may sound like control head but having a scantool to be able to view hvac data will be needed to know for sure. Let me know if you have questions, thanks.
I think it may be worth the gamble with pressure sensor, let me know how it turns out. Thanks.
Is fuse blown again?
Nevermind, I see that you said fuse is good.
Check to see if black/white wire going to coil has 12v with key in start position, let me know. Thanks.
Sounds good, let me know. Thanks.
Replace the coil relay and let me know if that helps. Also, are you using a 15 amp fuse?
Ok, let me know. Otherwise I'd imagine one of the coils are pulling too many amps. Does it start when only leaving 3 coils plugged in? Do coils seem to be getting hot?
If coils are getting hot I think you burned you PCM when you jumped pressure switch. New PCM needs to be install/programmed at dealership. The PCM is what activates the coils so if they are getting hot this would mean PCM is trying to activate them at all times. This is about a $600 repair at dealership which is probably your next best option. Let me know how it goes or if you run into questions, thanks.
Is vehicle auto or manual transmission? 2 door or 4 door? I can give you part number incase they try to charge arm and a leg for part.
Part number I have is 37820RNA68, it looks like these are also alternative numbers. 37820-RNA-A63; 37820-RNA-A64; 37820-RNA-A65; 37820-RNA-A66; 37820-RNA-A67; 37820RNAA67. I'm seeing some cheap ones on ebay but make sure dealership is able to reprogram a used on before buying if that is the route you take. Let me know how it goes, thanks .
It is about a hour labor to install/program. It cannot be programmed without being installed and dealer is pretty much only option. So first thing I'd do is call dealer and ask how much to have a new ECM installed/programmed and cost of part. If part is a crazy amount ask if they can reprogram a used one. If so, order one and have them install/program it. Let me know how it goes, thanks.
No problem, keep me updated.
