#2 of 37 Bubble, bubble by martens Jan 15, 2006 (1:46 pm)
Our '98 GM makes a gurgling sound behind the passenger-side dashboard when the car is accelerating. This occurs in all conditions, whether air conditioner or heater is on. Is this something in the heater core and can I fix it myself in some way without too much trouble? Thanks. Chris.

Replying to: euphonium (Jan 15, 2006 10:36 pm) Where do you add water on a '94 Crown Vic? In the overflow container? Replies to this message: euphonium (Jun 22, 2006 7:51 pm) p2min (Jun 27, 2006 1:48 pm) euphonium (Jun 28, 2006 12:55 pm)

Replying to: p2min (Jun 22, 2006 2:15 pm) Yep, after you unscrew the top - fill it to the line leaving a little room at the top for possible overflow. The coolant is anti freeze 50% and H2O 50%. The H2O evaporates in time requiring the overflow container to have water added. Replies to this message: p2min (Jun 27, 2006 1:48 pm) euphonium (Jun 28, 2006 12:55 pm)

Replying to: euphonium (Jun 22, 2006 7:51 pm) Thanks. I changed the thermostat in this car yesterday, filled it with the 50/50 mixture and it drove cool. However, when I stopped and started again I had puddle of fluid directly under the car, but not near the radiator. What could this be? Replies to this message: euphonium (Jun 28, 2006 12:55 pm)

Replying to: p2min (Jun 27, 2006 1:48 pm) Marsha is correct if the fluid color is same as coolant.   If the fluid on the floor is clear, it is probably condensation from the A/C system, which is normal.
#9 of 37 Fan has mind of its own by vmon Jun 26, 2006 (7:03 am)
I have a 2003 CVLX. The fan will not blow air from vent. It changes between floor and defrost for unknown reasons. it does not matter if it is heat or AC. It switches with notice or any action on my part. Has anyone experienced this?   vmon Replies to this message: cabinetpro (Apr 14, 2007 10:44 am) hag100 (Jul 12, 2009 11:31 am)
#10 of 37 Cheap & Easy Fix for EATC Blower Operation Problem by mr5x5 Mar 21, 2007 (12:14 pm)
I have been searching the Forums on www.crownvic.net and fiddling around with the EATC System Blower Motor Controller circuit on our 2001 GM LS for a year trying to solve the (initially) intermittent operation of the Blower for a year. After running with the Blower hot-wired thru a toggle switch for six months (when the intermittent problem went to complete failure)I finally got around to pulling the Controller Board out of the Heater/AC box last week. On my last search of the www.crownvic.net Forums I turned-up a note from a fellow who said "[i]most guys just fix it with a little bit of solder[/i]" this turned-on a lightbulb for me and today I had a look at the solder-joints where the connector is attached to the Controller Board. Sure enough, I could see that the solder was cracked at one of the big lugs of the connector! I heated-up the pins at all 5 connector lugs and flowed a little solder into the "gaps" around the pins. When I plugged the Board into the harness I found I have a Blower that once again works under control of the EATC! Now all I have to do is re-install the Board into the Heater/AC Box - a real tight squeeze. Right now I have it tie-wrapped to something under the hood but the heat sink on the Power Transistor gets REAL HOT - I think the best place in it is back inside that Heater/AC Box...
