i have a 2000 cadillac deville with 123,000 miles base model

push offand warmer buttons on the a/c panel.hold them untill all segments light release write the codes down and come back.

I just had all the codes cleared at autozone.so i dont no if that will work,allso push off warmerbuttons aon a/c panels what??????

i was telling u how to check your codes thats all.

But i dont understand what u are saying u said puzh off an push warm button on AC UNIT I DONT UNDERSTAND THAT I HAVE TRYED TO DO ALL that i thought u ment and nothing

Current codes IPM B0408 -IPM B0423- IPM B0428. PCM B0420.... The rest are history a lot allmost to many to list 30 history codes to list would like me to list them?

your going to the parts store and get all the codes cleared.then u have to check out the codes that wont clear or they reset.youll get no where trying to fix all them codes.

I just gave u all the current codes,an i asked would u like me to list the history codes?i guess i wont here from u till tomorrow, i also asked for pacific details on how to pull codes cause what u told me didnt work but u didnt answer that question either i dont understand??? cause my questions are not being answered an i dont get a response but mabey once a day if u look at my question history an the answers u gave me an the time we spent on topics its not working please dont get me wrong because i an we appritiate what u are doing. But i will find out what these codes mean somewere else i guess,cause u never told me what they mean u never told me why my alternator is messing up or could that b a direct result on the fuse situation, i asked about transmission an the fluid being over filled but i never recieved an answer about that so i dont no?????? LOOK AT OUR QUETION HISTORY??

Please excuse spelling my keyboard is sticking bad, especially when i want to type fast with large statements please if u would responed to previous questions thanks again:-):-):-)

sorry im disabled and cant stay on long.what u need to do is clear all the codes.then see what comes back current.wipe all the history codes out.any parts store can do this.then u knock them out 1 by 1.

O ok then thanks

An i did figue out how to clear all the codes so i will just wait a few days an see what comes back.

how did u clear them?ill be here drive it then we can make a game plan.gl

I cleared them with the cars diagnostic center clear all codes i entered yes!

u have to enter through pushing the off and warmer buttons right.

I dont no what a warmer button is i have a 2000 cadillac deville i did hit the off an info button an thats how i cleared them

if your alt. is still bad we can repair it.

It say no codes for allot of stuff like no rim code, no ddm code, no amp code, ect,ect. Current codes that came back so far are ipm b0408 ipm b0423 ipm b0428. Sdm b0041 thats all so far i cleared yesterday at 8pm an hadent riden the car that much just to the store mabey 8 miles in all.

This alternator is crazy im sittin outside now running the car an with the car running the battery is at 12v its normally says 14v an if i turn on A.C IT will fall to like 10.5 or lower i dont no what happened i wanted to no if it had anything to do withe them fuses i put the other day? I took them fuses out.

But if i rev the motor the alternator will start charging to 14 v

these codes were current and were never erased most likly.ill look these up and get back with u tomarrow.kk

B0423 air mix door #2 inop. B0041 l/f drivers side
deployment open loop maybe covered by cad. on service bulltin.
bo428 air mix door #3 inop.
bo408 temp.control#1 main front circuit malfuntion u have no engine codes yet.

Ok i no about the acuators i dont care about that i bypassed all of that but ok i will wait a lil while. But again why did my alternator go crazy is it because of the fuses i put in i just want to no why i done asked u 5 times already cause i didnt have no alt problems until i put those big fuses in an alot of lights came on an my alt actually whent dead for a day then the alt started chargeing the the charge is not rite its flucuating it charges then it stops then charges again it does this very fast why an how can i fix this.

i cant tell u what happened.without having the wiring circuit chart.u have caused this by installing those fuses i think.just remove the alt. and rebuild it.whats the problem it only 3 parts.you need to have a load test on the alt.and it shows how many amps. the alt.will put out.its not supposed to charge at idles only when u are driving.your voltages are low sok i would rebuild the alt.

Ok,how are u feeling today?

hang in their.ty for asking.i worked at cadie dealer my whole career.if u need help rebuilding the alt.im here

Yea i also wanted to tell u that i hear a engine noise like the sound u would hear in a radio but i hear it with the radio off? WHAT would that noise b it happen when the alt started messing up,when i put those fuses in.its like a light hum whistle the more i hit the gas the louder it is! NOW ITS NOT KILLING ME i just never heard it before, thanks so much......

poss.a bad alt. diode in the alt.

sorry i was falling a sleep and waking up on the last response.lol it was 2 am.are u talking about static? is it coming from the left or right or center engine compartment?use a long screw or a long wooden dowel. u can get this at the arts and craft store.use 1 to put on componates and then you put the stick to your ear.the sound will travel up to your ear as you rest your ear on it. then u can locate it by reving the engine and trying different componites.including all the pullys and parts the belt operates.when u find it itll shoot right to your ear. falling asleep again ill talk to u later.tiil then my friend.

How are u hope fine, got a question i just installed the two rear shocks,hook the airline back up (levelride) ect. An i dont see any differance nothin at all i never did find the relay or green light for levelride but i do hear the compressor when it comes on, it comes on everytime i start the car an stays on for about 3-5sec, i just dont see why i spent all this money replaceing shocks with no results at all?????? THANKS MUCH.
