SOURCE: The windows in the 95 oldsmobile cutlass ciera won't work at all

maybe the wire is severed where the door (drver dr) pivots. thats what was wrong with mine. there is a rubber boot with crinkles in it that hold all the wires together. you can also try replacing the switch board that controls the wndws on the drvr dr. hope that helps.

SOURCE: Heater core burned out and I want to bypass the coolant hoses.

Without knowing your car specifically I can suggest the generic way to do it. Locate the two heater hoses going into the firewall, probably on the passenger side. They're the ones that get hot and are about an inch + in diameter. Disconnect. Measure the inside diameter of the hose and purchase a short piece of galvanized or copper pipe (6 inches) at Home Depot. Connect both ends of the hoses to the pipe to form a loop. Secure the hoses so they don't land some place that would cause a problem.

I had this problem on an 85 Tbird. I had heard about a product called Bars Leak and tried it. It worked. No leaks and I kept my heater. You should be able to find it at any parts place at less than $10. Ground black pepper also has worked for me.

SOURCE: How do you replace heater core in a 1993 olds

First off, you want to drain the coolant until it is at a level below the heater core. Then you want to remove your glovebox screws and the entire assembly. It may be necessary to remove the far right passenger side kneepad retaining bolt/nut.Disconnect all vacuum and electricle connections.It's a very good idea to take some digital pix during the process to assure proper reassembly.Remove both heater hoses keeping track of which went where. Back inside look around for all the housing bolts for the heater/ airflow control box.If you have AC it is not necessary to discharge the system.Remove all the housing bolts(some may be attached from the outside. I cannot, from here explain the location of each bolt, you'll have to keep looking until you find them all.I did neglect to mention to remove any cable driven door connectors also, if it is so equipt. Put an old towel on the floor of the vehicle because there is inevitably going to be a spill of coolant. When the housing is completely free "roll" it out from under the dash as far as posible and you'll see the heater core opening cover. It will have the two hose tubes sticking out, you couldn't miss it if you closed your eyes...lol Remove the 5-6 screws and slide the core upwards. You'll know how to reassemble the unit by using your pix as a reference. Good luck my friend, I hope this was as helpful as needed. Dana

Only warm air comes out of heater on 89 cutlass ciera core blew out, new thermostat what controls air temp in heater system. Lever moves from cold to hot easily but can't tell if it moves anything under...


#1 Listen if you hear the blend door flap open and close if you do then working good.

#2 run car to normal temp and touch both heater hoses and make sure temp is similar if one is hot and the other warm then your heater core is clogged and most likely that can be the problem it build lime from having tap or well water in coolant system distilled water is recommended but who uses that.

#3 run car when cold with cap off @ 2k rpm and top off radiator. Then close cap and continue to rev @2k until normal temp if heater hoses are not equal in temp heater core clogged.

I need a simple way to change the heater core in a cutlass supreme.


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

Need to replace the heater core


This can be a real challenge. The heater core may be under the dashboard. Check under the hood where the heater hoses go into the cabin. If there are bolts there , you be lucky and it may be possible to chqnge it from the firewall side.
