I got it all worked now

 

Got a quick question, didn't really have the patience to look through 20 pages of replies so I am sorry if it has already been asked. But any tips on getting the 3 connectors behind the radio? Attempted today and get up to the 3 white connectors in the back but couldn't reach nor could I figure out which way to unplug the top on. Thanks in advance.

 

Give yourself more room by removing the center top vents. It's secured by only two screw below once you have the radio unit loose.

 

Which one is the display cable? I just attempted the fix myself and when I put everyhting back together, except the ashtray, I had no display. When I started the car there was no "Mazda RX8" thing and no lights like normal. I then turned on the heater and i had it on for about a minute and no hot air yet, then again the engine was cold still so that's probably what it was. But I can not test if the solder job I did worked because I have no display. I then disconnected the radio again and reconnected and now my hazards don't work where previously they did. Any suggestions?

 

Thanks a lot. Surprised I didn't realize that before. Dope

 

This tut worked great. Followed exactly how it goes and no problems hear works great! Thanks!!

 

Just did this worked flawlessly also touched up a few other solder points I seen that look suspect and redid them just to safe.

Thank for the info!

 

Great DYI. I was able to follow this and fix my heat. thanks so much

can someone please let me know everything i should know about this car ??? i just got one 4 months ago and i dont know a lot of things

 

Ok I have a question how can I do the heat/cold **** test if I don't have a stock radio. I have a metra kit with a double din and right now I am getting just heat. Some times I'll get some cold air but mostly just heat. I have ckeck all my connections and they are good.

 

ok well the concept might just be the same. Power Seek. Simple as that. Your heat. Is it only on one side of the car? i.e. passenger, drivers side. Also if you cannot do the test, just remove the heater control ***** it's really not that difficult and look. Once you have it all disasembled on the board itself you will see three solder points in a row. That is where it usually cracks due to it being Shi**Y cold solder. Anyway. remove old solder, clean, re solder. If that dont work, Flush your heater core.

start there.

 

I did take apart the controls but the welds look good. They are pretty small so maybe I did not see the crack if it is crack thats why I want to do the test. Oh and it's heal in both sides. I want to make sure that it's either the controls or the metra box. Before I do anything.

 

Do these cars have a valve on one of the heater hose that close and opens. I know on hondas it has one on the engine bay and it's what controls the heat. Sometimes when the ***** or cable breaks we just did it manually in the valve itself

 

Hlover1- usually it's not that easy to see if they are cracked. Take a closer look, wiggle them. Personally, i would remove the solder and redo it anyway since as we all know it IS destined to fail if it's cold solder.

 

This saved me ages ago but I never got around to saying... Thank you so much!

 

My heat decided to go in the middle of a snowy day with bitter cold. It sucked hard. I had to keep one hand warm at a time by turning on the seat heaters and sitting on them. This fix worked like a charm but those connecters were a PITA.

 

thanks!

 

So I did exactly what the write up said to do and now I get nothing but heat most of time and cold sometimes at random positions of the ****. Any idea what I could do now? Thanks

 

AWESOME DIY!!! Worked like a charm! Thanks.

 

Anyone done a uk spec heater board. The dials are soldered in place. I resoldered all accessible joints around the control ****. When turned you get 3-4 meg then 0.6ohm all the way around alternately. Same as the fan control that still works. I did manage to fix the bose changer while i was in there so not a total blow out exercise. Any ideas chaps. I hate buying new parts if its fixable!!
Cheers in advance.

 

Sweeeeet i did this watching fox news about the missing plain... Worked great thank you....

 

Worked like a champ! Took longer to remove the focking connectors then it did to do everything else..... Amazing how much easier it is to put them back together than take them apart.... :-) Thanks for the write up!

 

I jut did this today and it worked amazingly. No more finnicking with the controls

 

Try back-stepping if you missed connecting the wires to the circuit board. Is your LCD screen working, do you know how to perform the A/C test?

Could you take pictures of your unit at each sides?
