Title: Need help on heater in car
Post by: Gina on February 02, 2011, 06:20:54 PM
I have a 04 Buick Rendevouz.  I turn on the heat and it works as long as I am gassing it/moving down the road.  Once I stop at a red light, cold air comes out of the vents.  Where is my hot air going? :censored:

Have you checked your coolant level recently?

You could have a faulty thermostat or possibly a clog/blockage in your heater core or cooling system.  A new thermostat is a cheap fix.  I have the same problem with my car (the coolant in the heater core eventually cools down if you're not moving). 

My radiator leaks noticeably as well.  You may want to make sure you're not leaving any green fluid behind when you drive away after parking somewhere.

Or possibly a loose belt, especially if it got wet, maybe not moving your water pump enough?  Being a cheapskate, I'd check coolant level, as chris said, and the belt first...

Yes, but they're not always foolproof.  I think my car only measures the fluid level in the overflow tank and not what's actually in the radiator.  So I could have a full overflow tank and still be missing half my coolant.

I'm lazy... I don't check my belts.  I probably should. :p

Could be a vacuum leak to the controller. Does the car idle rough or miss on acceleration?

How many miles do you have on your '04?

now sometimes when I take off it feels like the transmission jerks, is that what you mean by miss on acceleration? 

and I have about 145k on it

Wow, that's a lot of miles.  I would swap out the thermostat eventually.  You can get one for ten dollars and you can probably change it with nothing more than a screwdriver.

Possibly.  I have a giant leak on my intake manifold and my car herks and jerks until you get past 20mph.  The symptoms would be similar.

I had that same problem once. Worked fine as long as I was moving. I think it needed the heater core cleaned, a new thermostat and some coolant.

I go through at least a gallon of coolant in a month.  I need a new radiator. :(

yeh, it seems to do it in 1st gear, 2nd gear, and a little in 3rd gear then it's fine.  And it picks when it decides to do it. I'll go a straight 3 months with no jerk and then all of a sudden it starts jerking and then disappears again.  Hmmmmmm....and here I thought I wrecked my tranny

I think if your transmission was behaving like that, you might have heard some other noises. 

Did I mention I loathe automatic transmissions?  Ugh.

It's not me.  I've picked up two in the time it took me to drive home from work.  Maybe someone got their feelings hurt. :bawl:

There.  I gave you a +1 for giving me something to do.

do you hear the sound of fluid gurgling in the area of your glove box?  If so, you have a coolant leak somewhere in the system that is sucking in air when you turn off the car and the engine cools. The air gets trapped in the heater core causing the gurgling noise.

Gina, in order of how I would diagnose this problem, if it were mine:

Coolant level

Thermostat

Intake manifold leak 

You can fiddle around with where you are directing the air, to see if it may be some sort of vacuum leak under the dash.  (try just your feet, then the windshield defrost, etc). 

I'm putting my money on an intake gasket failure, although for your sake, I hope it is as simple as coolant replenishment.  :cheersmate:
