I have an 88 DeVille. I don't drive the car often, but I do start it every week or so and let it run to keep up the battery. This morning I sat in it and ran the climate control on 90 degrees AUTO (chilly outside). I probably let the car run 45 minutes or so while I listened to the CD player, wiped down the interior, etc. When I finished, I noticed water dripping from under the hood -- actually at the cowl/windshield area near the front passenger tire (almost underneath the antenna area). The fluid was clear and cool. I realize it looks like typical A/C run off, but why this drip when the heat was running? This car has been converted to the new A/C system, so is that the reason? Never a problem with anything on this car ... just wondered why the water drip. Thanks!

 

I would consider it something normal for the cir***stances, check the fluid level in the radiator and check again when you next drive the car for any period at all.

 

In a climate control vehicle the de-humidifier runs with the heater just like it does with A/C on.

 

FYI, just starting the car and leaving idle is not the way to keep your battery charged.

 

Gary, i missed all that.

theatreman,

one will do more damage to a car doing that, not to mention the cost of fuel.
a full time battery tender or connecting a battery charger every couple
of weeks would be a much healthier solution. also, the fuel you will
save will easily pay for a battery tender or a charger

each time you start the engine and dont bring all systems up to running temp
along with the trani, you add moisture and corrosive elements to
the crankcase, the exhaust sytem, and as you found out the ambient
control/AC system.
that will kill the car over time.


the 2nd option is to simply disconnect the battery as it will kep its charge
for several months if there is no current withdraws -

option 3
if you really must ran the engine, drive the car around the block for 20+
minutes, bring the trani to temp, make darn sure you run the A/C to wet
all the refrigerant seals, operate every switch in the car to assure oxidation
does not ac***ulate on the contacts.
