    no there is no sloshing but they had bypassed the heating core and it would still leak is that possible and could the a/c pipe be that high up I know where it should be located but there is nothing there?

If its the heater core then the mechanic pressurized the cooling system at the radiator or coolant bottle, If it did not hold pressure thats why he's recommending the heater core. And it does not have to smell. Now we can guess all you want but he's the one that looked . Since we don't know what the complaint is noone can make a call on whats wrong. If your loosing coolant then it has nothing to do with the AC.

The AC condenstion drain is under the truck on the passenger side at base of engine firewall, has a rubber one way valve on it, about 3/4" in diameter, the tube u speak of is not it. do u hear a sloshing in the heater ducts? you don't always have the smell, have seen cores leak very slowly and no smell.

    Gesh give me a little time to answer, the heater core takes about 2 hours to replace and the part is about $60 US, so the job should go for about $250 in my shop. here is the procedure if u want to do it yourself, but have you crawled under the truck and checked the drain for the water condensation from the ac evaporator core, i think not, do that 1st.

    know that you have to remove the glove box to be able to get too it but further than that I will not know until next month when we have the money to fix ours..... I will let you know then...LOL

    found out the drain is not visiable, but is where i said it was.

    There is a drain spout hidden underneath a shiny drain guide on the passenger side of the vehicle. It is located directly above the exhaust pipe

Sticky fluid on passenger floor

That sweet smell is usually, radiator coolant. Most likely you have a leak on the hose or the heater core is damaged and leaking.

Why does heater smell sweet

Hi yu heater smelling sweet is not a good thing. There is an engine coolant leak probably in the heater core and the smell your noticing is aspirated ainti-freeze. Check your engine coolant. It should be slowly lowering. The only fix is to have the heater core replaced. You can for the moment bypass the heater core by looing the hoses together with a nipple on the engine side of the firewall but you will have no heat or heated defrosting abilities until you replace the heater core.

Thanks for choosing FixYa.

Heater core 1987 lichon signature 5.o location

heater core is located on the front passenger side next to your ac evaporator assembly, your heater unit uses engine coolant water as a heater , the reason why you smell anti freeze because your core has a leak.
you can disassemble the unit if you have the right tool and by removing the front glove box and console panel to expose and give way to check that unit, it normally fastened by screws and a few bolts and nuts.

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on

Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment.
Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak.
Good luck !

Sweet smell inside car and moisture on inside of windshield

This is probably a leaking heater core, which will need to be replaced. The sweet smell is the coolant (antifreeze).

If you notice a 'sweet' smell, or windows tend to fog up, it's your cars heater core leaking. The heater core is located under the dash, passenger side, it's like a mini radiator. The cars cooling system directs hot coolant to it so you can have heat. To change it is an involved procedure.
If there is no evidence of the anti-freeze smell or windows fogging up, and u have been using your air conditioner, it would be a blockage in the drain tube from the a/c. The end of the tube is located under the car on the passenger side , behind the front wheel. The blockage needs to be removed, and will solve the problem. Let me know what u find Curt

Heating in my car

There is a valve that controls the hot water into the vehicle heat exchanger which is on the cab side of the firewall. The device is controlled mechanically with a push-pull cable , by vacuum control or electro-mechanically by a servo actuator.
There are most likely TWO pipes that come from the engine radiator and go through the firewall, rear wall of the engine compartment, into the passenger cab area. The Heat exchanger control valve is
mounted somewhere along the path of ONE of those pipes or tubes (the "input" tube).
There are many threads on the Internet on this vehicle and year, and so many concern heating/cooling.
I would suggest getting or borrowing a $20-25 manual on the car and going to the body section and
tracing either the vacuum diagram or the heating control section to find the valve and also the dash controls. Something is disconnected or broken with either one of the three methods described.

This assumes all else is OK and NO COOLANT leaked into the Oil (frothy Oil on dipstick)
and no Transmission Fluid is in the Coolant (oily color reddish in the Coolant with oil smell instead of sugary sweet smell) ; if the coolant system integrity is compromised in any way as described; stop -> go to a mechanic <-; increasing damage is imminent.

If its just a control issue, you can probably set the valve up at 1/2 open if its a mechanical type with push-pull cable; I have done this on several cars when the control cable rusts; disconnect the valve end and set it manually 1/2 or 3/4 for the winter
