SOURCE: ac/heater control module

I have a 1989 Olds 98 Reg. Bro. I have recently located my ac control module under the hood on the firewall. removing it should take about 20 mins depending on whats in the way. but to cost to replace is the kicker. I found the part @ NAPA for $240.00. may i suggest craigslist.org and look under parts for your car or one like it. the car made like mine would be a 1989 Cadillac DeVille. I hope this helps.

SOURCE: Replacing heater core in 2000 GMC sonoma. Dash is

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana

I have replasteb the heater/ac blowermoter and restester checked the bender door working and the ac/heater is still not working Why isn't it working????


What exactly isn't working? the blower motor? If so then you may need a new blower motor harness from the switch to the blower, the connector burn up (under sized wiring) at the dash control head, you will also need a new blower speed control switch.

Do I need to drop dashboard to reconnect I'm guessing black vacuum line that controls my ac and heat control? 2003 NAVI


This may not be bad. There should be a trim ring around the control panel. I think. You may be able to connect from under the dash. Most Ford or L/M products have screws or tabs that connect the "curve" that. covers wires etc. The curve is the piece that swoops toward firewall. All, or most are still vacuum controlled, I'm pretty sure that control module comes out in one piece. FYI, I use U-TUBE for many fixes.

How to replaced a 2003 Malibu heater switch


Center instrument panel trim bezel-- on models where the ignition switch is mounted behind this bezel, use a small, taped screw driver to pry off around ignition switch. the switch stays in the dash. pry around the trim bezel with a flat tool to remove trim. to release the clips. ( Be careful not to break the trim around the controls). Remove the screws from heater assembly, and pull out just far enough to remove vacuum hoses and electrical connections. Use a small screw driver to release the clips from assembly. When installing switch, Do not use oil on the hoses to make them slip on better. it will mess up the vacuum needed for proper operation. If needed use water for the hoses.Good-Day!

How do I replace the blower switch in the dash without breaking up the dash


Are you sure that you need a blower switch? There are other items that are prone to going out before the switch like the resistor or the motor, but if it is the switch you first remove the large piece of trim that surrounds the radio, heater controls, and instrument cluster. This will reveal the screws that hold the heater control head into the dash.

Ac problem


I just fixed mine. same problem, no ac light no fan. inside the heater control assembly there is a electric wiper arm on the fan switch. This arm connects all power for fan and ac. Mine broke out of the fan control switch. Dash is not too much problem to get out. Have to pull top dash center section out by puching forward and lifting out. pull all screws on center dash counsel. remove radio, two side covers that hide screwsand lower trim that holds emergency flasher switch. remove cables from heater control and wires and remove. Took me about an hour. The code on radio will need to be reset so make sure you have that handy. Hope this helps..

How do I replace a 1995 GMC Sierra A/C Heater Control Assembly?


If you have tilt stearing, lower the stearing wheel. Carefully remove the dash trim around the instrument panel and radio a/c controls. Unplug the headlight and truck bed light switches. Lay the trim panel aside. On the side of the control module gently slide a flat screwdriver in the slot until the clip disengages. (Look at the new one to see which way the clips face.) Repeat on other side. Disconnect wire harness plugs. Assembly for the new module is the reverse of the above. Be careful to use gentle pressure on the dash trim or it may break.

I am seeking location of ignition switch wiring on 2000 olds intrigue.  I have under dash removed.


Disconnect Car Battery
I replaced the ignition switch in my wifes 2000 intrigue. (ignition mounted in front dash). I had to take off the knee bump trim and the trim around the instrument housing and remove the instrument cluster. Leave it connected and just lay it on the dash. You also need to remove the radio to get to one of the screws that hold the ignition switch module. Once you get that loose you can pull it out so you can disconnect the wires going to it.
If you need to replace the ignition module insert the key and turn to accessories, there is a small metal button to push in, then your key and the lock part will fall out to install into your knew ignition module. At that time you can also remove the cruise control cable.
I am not a mechanic and the whole process only took me an hour or so.
I replaced my ignition module to fix the heater and AC operation. It also fixed the cruise control that hadn't worked for a year.
