Wideband in hvac
i was wondering if anyone had pics of this i know people have done it and i did mine but i have like a cm between the gauge and the waterfall ...i want pics or maybe a diy
i know that people have also relocted the hvac controller that controls the hot or cold, d like a diy on this

opps my bad, that is not my car, that is rythmnsmokes car. He said he moved the know over to the left side of the steering wheel, but never hooked it up

yes this would be the best idea and works but......LOL i um...in the process of removing the potentiometer i broke th eunit, the board is fine but not the potentiometer, anything else i can use? maybe something from radio shack
mine, not wideband but egt gauge


ac still works.. question for engifineer or any electronics guru, how come the temp control doesnt work like i cant switch it to hot? all is well connected and hardwired, maybe some change of resistance due to longer wires?

Should still work. The wire resistance should be negligible. Did you run a wire from the body of the pot to the mounting points on the board? This grounds the body of the potentiometer to the control board. Should work without it, but I have seen circuits that are set up to need that.
Otherwise, I would just double check the wiring.

thats what i thought but after few tries going to through the solder joints, i dont seem to see the problem. What I did though is, i did not remove the potentiometer from the board.. i soldered some wires to the solder points at the back of the solder board.. i ran the wires towards the glove box and soldered it to an extra potentiometer with a **** attached to it.. the ac worked but the temp control doesnt. Then I tried soldering those wires from the hvac to an extra hvac on the glove box, potentiometer is still on the board i just soldered the wires from the pins at the back.. im gonna go through it again
Um wow! So If i could see it it might work better. But so you took a different potentiometer and wired it up to the original potentiometer and put the other one in the glove box? And now u have a spare hvac controller potentiometer wired up in the glove box? Thats what I am gatherign from that. But maybe the potentiometer is incorrect voltage or your original potentiometer is turned to cold and turning the other one wont do anything! Its kinda hard to troubleshoot without actually seeing it and not being able to take measurements.
hey i just got mine done, i soldered three wires to the soldering point and ran them to 2 switches ...heres a digram
i ran a switch from pink to blue and a switch for pink to red*NOTE* this wont work if the potentiometer is still in place

yes thats what i did.. that might be the case, the potentiometer that is still on the circuit board is still the one controlling the temp.. ill try to redo it when i get a chance. i wasnt really concerned with it coz i almost never use heater here.. but then i realized without heater i dont have a defogger lol.
so the temp control still works? you still have to shave that thing for the **** though otherwise the gauge wont fit. or you can take out the whole potentiometer.. it just a pain to remove it or even solder the wires when its off
yea i completely removed the potentiometer, and soldering the wire wasnt too hard i got 2 wire through and heated it and the solder stuck ...but one one wire the wire didnt wanna go through the board so i just made a mound of solder and fused the wire into it
Dont use a mound of solder.. the connection will fail at some point. Make the connection proper.
The reason you are having issues Ace is because you now have two pots in parallel. This will cause a reduction in overall resistance (and really throw off the voltage divider) and cause the circuit to not operate properly. You need to remove the original pot and relocate it. If you remove it and use the one you added, you need to make sure the one you added has the same resistance as the one on the board.

yeah im gonna do that down the road, not really a concern right now. The reason i did it that way is, with the potentiometer off the circuit board the solder points on it is very tiny and makes the joints very vulnerable.. thought I would do perfectly with it not removed.. but really my main goal was to get the ac working at coolest
