TooManyProjects Posted April 7 Share Posted April 7 I have an 89 eliminator that had a fire in the heater box which destroyed the box, dash and wiring. The most readily available stuff I can find is from a 92. Is the wiring completely different or is it a direct swap? Quote Link to post Share on other sites
Torq_Shep Posted April 7 Share Posted April 7 It should be a direct swap except there are some differences between the plug styles on the blower motors and there is a thermocouple (not sure it's purpose) that is different between 89 and 92. I hacked together a 1988 box and a 1991 box in my truck and those were the only 2 noted differences. Quote Link to post Share on other sites
Gjeep Posted April 7 Share Posted April 7 Box is the same, components are different. 92 and 89 components don't play together. You need Renix goodies. Quote Link to post Share on other sites
scaleless Posted April 7 Share Posted April 7 This is the thermocouple Torq is referring to. It releases the compressor clutch when the evaporator temp drops below a certain amount. Ignore the bubba job here - someone replaced it and had no idea what they were doing. It's upside-down and the vapor line needs to go all the way into the evaporator. I just replaced the blower resistor in mine and RockAuto shows the same part #s for both 87 and 92 so I don't think that's different, unless my blower doesn't work and I have yet to find out, ha!

eaglescout526 Posted April 7 Share Posted April 7 I know this isn’t entirely relevant but some people may have 84-86 stuff and might list it for all years. 84-86 used a different plug for the main harness and the vac lines and what not are all different. Quote Link to post Share on other sites
TooManyProjects Posted April 7 Author Share Posted April 7 So 87, 88 and 89 is direct swap? Well I guess I’ll keep looking! Thanks! Quote Link to post Share on other sites
scaleless Posted April 7 Share Posted April 7 '90, too, I think. Quote Link to post Share on other sites
Minuit Posted April 7 Share Posted April 7 I have a 96 blower motor in my 89. It plugged right in. That's something that I honestly suggest replacing with new unless you need one badly and have a spare, anyway. The thermal probe's purpose is to regulate the system by cycling the compressor off when the evaporator is below a certain temperature. You need it. The probe is different between HO and Renix.

TooManyProjects Posted Saturday at 12:25 PM Author Share Posted Saturday at 12:25 PM SCORE!!! Just found an 89 XJ at a local yard! Got the HVAC box, whole dash, tilt column and wiper cowl for $150!!! Quote Link to post Share on other sites
