Like the title states. Ideas? Rads full not leaking, heater core? Lost intermitents on the wipers awhile ago, now only fast works and they won't "park" when turned off. But the horn still works lol

Wipers is most likely the delay module. It's a little black box velcroed to a tin plate on the bottom of the dash by the steering column. You can unplug it and plug the 2 ends of the wiring harnesses together to get low speed back.

On the heater, if you're saying the fan is blowing but no heat most likely the core is plugged. Also check the temp control cable and door lever. It's the one at the middle of the heater box facing out to the seats

Fan is blowing, hi and lo. Engine temp is staying cool so not sure how much heat there is to be had. I'll check the heater box.

Thanks for the tip on the wipers.

I got your wiper module here, can't sacrifice the heater core tho as I'm adding that to the willy's build.

If the engine isn't really getting warm the thermostat is probably screwed, not an uncommon thing for a 4.0L

take the thermostat out and boil it in a pot of water and watch to see if it opens up or not
