I have a 1984 TA with a weeping heater core. I disconnected the core from in front of the firewall witha loop around early this summer - but now it is cold and I need to install the new one I have purchased. This evening I took off all of the lower panels, the dash, the guage console, the center console, and all of the switches connected thereto( rear defrost switch & headlights ) What I have found is that I still cannot seem to get a clear view of what I'm needing to see. Do I need to take off the plastic dash support / air router that runs from left to right across the entire passenger compartment? It seems as if I'll have to drop the steering column to facilitate this. It also looks as if the plastic support structure is riveted to the metal frame. Do I need to grind these off and re-attach them when I'm done. It looks like at one time someone took a recip saw and replaced the section over on the left by the light swith female adapters. Does anyone know how to go about this? I read through the archives...It looks like I'm making a whole lotta work out of a 3 hour job.......Frustrated in Nashville.

just did that job 3 months ago... take out everything. this is more like an 8 hour job.
remove the following.

top pad, radio and pod, guage cluster, front speakers,ecm, center console, remove bolts from steering colum and drop that too, you can leave the upper ducts attched to the plastic dash support if u wish..you may get lucky when you unscrew the dash support from car chasis to jimmy enough room to get at heater box. one thing I can tell you is there is no cutting of rivits to get at heater core. unless GM changed dash in 1989 turbo TA

 

P.S this is good time to clean all componets of dash u would be suprised how much filth you'll find

 

This one's going to Body and Interior.
