heater output 90 yj
Alright, I bought my yj about a month ago. The heater didnt really put out, like it did on my 94, so I did the 73 blazer upgrade. The blower is definitely stronger, there is no doubt. But the air I actually get from the vents is miniscule. I dealt with it for a little while, but i had to plug a few holes in the floorboards, so I figured why not pull the box. So I took it out, took it apart everything seems to be working fine inside. The doors seem to work just fine. So I siliconed the entire seal, bolted it back together. I gave it time to dry and reinstalled. I still have little air flow from the floor vents, and the defrost vent. Since it is getting warmer here in the northeast, I wont worry too much about it, but when fall comes around, and old man winter joins the fight, I want this fixed. My 94 would heat up great. the air is hot coming out, but its like there isnt any force behind it. thats the whole reason I did the upgrade. whats happening here? there are only two doors inside, i played with the door my the floor/defrost and it gave a little more air, but still not what it should be. I am lost guys. anyone have any ideas? i thought about swapping the box out, if i can find one at a junk yard. i just dont know what else to do. oh, when i did the initial upgrade, the blower i got had a little too long of a shaft. so the ridge inside the box on the back side of the fan, i cut it down so the fan would fit. i dont think this would matter but who knows. let me know. thanks!
