    Ok
    So I bypassed the heater core and everything seems fine

    AC seems colder, hmmmm???

    The coolant got up to 235* tho but I think the driver side cooling fan went out again bc it took about 30minutes to creep up there and it was up and down (228*/235*) with stop n go traffic

    Checked coolant level about an hour after I got to work , had a lil pressure still when i took off the cap and was still full so I'm guessing no serious leak

    235 is a tad high. Keep an eye on it.

    If one fan runs when you fool with the wires, what makes you think new fans will behave any differently ?? It's time for a thorough wiring, connector, and relay check BEFORE spending $200 or so on new fans/motors.

    Here's your wiring diagram. Right click it, save as, and save it to a temp file or flash drive, zoom it out and print it. (Use a real computer - not some dinky smart phone app - can you even print from a cell phone ?)

    Thanks Sub

    And yes u can print from most any iOS or Android phone thru wifi or Bluetooth if the device/printer has those options, most do

    With my iPhone, I can actually save the photo and zoom, minimize, cut, crop, enhance, Print on your Unlocked Printer if its in range etc . And that's with the iPhones basic features... No apps

    Good to know ............. My OLD (ancient) Nokia makes/receives calls and that's about it. Karen and I together use less than 15 minutes a month of cell time.............. I actually use a bit more in the STS OnStar system - 16 minutes last month.

    Ok...

    So the passenger side fan plug/connector looks burnt

    I cleaned it as best i could but its obviously been cooking (shorting out) for some time

    I repositioned and tie strapped it to the metal post between the two fans so that it gets current and Both fans come on

    So now, do I replace the plug (how) or do I replace the whole passenger fan???

    well - you have diagnosed the problem as a bad plug -

    so I would plan on just replacing the burned up plug -

    HOW?

    couple choices -

    go to the boneyard - locate a similar car - cut off the electrical plug you need -
    cut off your screwed up plug - splice in the other good used plug -

    OR -

    go to rockauto.com - put in your car information -

    go down the parts list to - and CLICK on
    Electrical-Connector

    go down Electrical-connector parts list to - and CLICK on
    Radiator Fan Motor Connector

    choose the one that looks like the one you need -

    --------------------

    you need to solder the wires - and cover them with shrink-tubing -

    Ah

    For now,
    I shall replace the plug

    I've decided to order some new cooling fans tho

    I noticed the passenger one is consumed by rust and the fan wobbles as it gets up to speed

    The other one took most of the impact from that accident I was in last year... Surprised it still worked and still to this day but ill feel more comfortable retiring the two and installing new plugs and fans

    They've done there job long enough and I can't risk anymore damage to my engine

    When i checked for codes I noticed i had the PCM P1258 code (protection mode active) which i believe is the Camel Mode ... and it did get me down the street and across the intersection at 15/20mph after the heater core blew out

    I can sure attest to its ability to keep the car moving... ... tho, I didn't drive it more than a mile...

    Anyways

    I wanna thank y'all for the help and direction on fixing the Super Lac Deville

    I was feeling like my best friend was about to die in the hospital and y'all gave me hope with each response

    Thanks so much everyone

    Re: Coolant Steam coming thru AC dash vent

    The plug is burnt because the blower is drawing too much resistance and over heating the plug. Bottom line is the blower is on it's way out. I'd replace both the blower and the plug. Otherwise you'll have to replace the plug again later when the blower finally goes. Pay me now or pay me later, your choice.
