Hi there,

Well the heater core is located under the dash on the passenger side, usually cased in a plastic housing.You may have to remove the glove box in order to have access to. And when you get to the point, when you are disconnecting the coolant lines and remove the core you use some clothes to protect the carpet as fluid may drip.
Post comments for further help or information........
Good Luck!!

Thanks for using FixYa!!

1986 buick lasabre heater fan workes, but no heat at all


could be a vacuum switch on the heater hose. The heater hoses are the small hoses ( 1inch, usually black or red) that run from the motor to the inside of the car. They should be warm when the car is up to temperature.

The vac switch controls the water flow to the heater core. If the vac valve is bad or the vac line that feeds it is bad it will not allow water to enter the heater core.

Could be a plugged heater core too.

Check the water level in the radiator as well. If the engine is low on water often the first to go is the heater.

Replace heater core on 1992 buick roadmaster


It appears I was incorrect about removing the dash assembly, here are the instructions from a Buick owners club.

Under the passenger dash is an access panel that will allow you to remove the heater core, it really isn't that hard, there are lots of little dash screws and panel screws to remove before you get where you need to be but at least it is roomy. The AC evaporator is located by the heater core. I will give you a tip. I changed mine last year and the heater core that I ordered for my 92 Roadmaster was not correct, when I took my old one out and matched it in a book at the local part store, the heater core for my vehicle was listed as a 96 Caprice???? The car has been in my family since it was purchased new and the heater core had never been changed!!!! Explain that one!Oh yeah, one more tip, if your heater core is leaking, this access panel lowers towards you, if there is nasty sweet smelling water in there it will pour all over you, be careful! Caprice parts are the same as a Roadmaster,so if you ever need anything just look up caprices
