88 comanche laredo insulation around heater fan

[gl1200aman]

The heater fan was blowing fuses so I bought a new one and while replacing it I noticed there is felt type insulation in the hole. I also found the shredded insulation filling the door under the dash on the pass. side. Where is this insulation from? Is a new replacement piece available and from where?

 

The main thing is to find out where the insulation is from. Is it from inside the heater housing?

Sounds like you have some mice in there tearing up your insulation and making a nest in the ductwork. :mad:

It may have in the past. I bought it a few months ago in Carson City, NV and the seller had very little history and I found out omitted or lied about the condition. Just hoping to find out if and where I can get a new piece and where it goes.

Youre asking for a new piece of insulation? If I were you, I wouldnt worry about it. It could be from your hood liner, or the firewall liner (in which case the dash would need to be pulled out), or from under the carpet/ rubber floor, or from in the seats, or from an outside source that has nothing to do with your truck. Chances are too that there is more of that stuff surrounding your heater core and or your evaporator, in which the only way to get it out is to pull the dashboard out and remove the heater AC assembly to clean it out. I did this whole job when I added AC to my 87. I used a whole can of lysol spraying the whole thing down after removal of all the crap from my donor heater AC unit. Good luck!

The insulation is all inside the heater core / a/c evaporator housing so I assumed there is some type of insulation inside the housing. I was hoping to find a new piece of insulation because as it is now I feel allot of heat while driving it. I already have a new carpet with backing I bought off ebay to install.
