ok so i just bought a used 91 cherokee and the blower motor does not run( no airflow on any setting). i have a new blower motor installed and a new blower motor resistor installed and still the fans do not work on any setting. I dont know what else could be the problem if you know pls help. Thanks
2000 XJ does not have good hot heat.
I noticed the temperature guage is not getting up to 210. it only gets up to about 120.
The blower motor was out and i had that replace along with a radiator flush and fill.
It does push warm air but think it should be warmer.
Any thoughts?

2) Did you turn on the defrost when you flushed the radiator, so that it would also flush the heater core?
3) How long ago did you do the flush? If it was only a day or two ago, it's possible there's still air trapped in the system.

1) Check the thermostat housing with an IR temp gun. 120 is crazy low unless your thermostats is stuck open in a polar region. I suspect your sending unit our gauge may be faulty.
2) Did you turn on the defrost when you flushed the radiator, so that it would also flush the heater core?
3) How long ago did you do the flush? If it was only a day or two ago, it's possible there's still air trapped in the system.

It is cold out, 15 degrees. I'll try the infra-red temp gun and see what temp I am really at. I know the temp gauge worked in summer as it ran at 210 all summer.

Transmission Neutral Park Starter interlock
I have a 87 XJ with intermittent starting problems. Sometimes it won't start in park but needs to be in neutral. I know there is an interlock switch but where is it located? Does it just need adjustment or cleaning?

They will honor their warranty too, the first one I got went bad about a year after I got it and they replaced it free of charge. You keep your warranty if you mail back the defective one too. 10 years free replacement works for me. Really beats paying $200+ for a mopar one!

Do you think I should replace the termostat or backflush the heater core first?

If it isn't getting up to operating temp, your thermostat isn't closing. Go ahead and spend a few extra dollars for the 195° stat at the dealership. They have better reliability than aftermarket ones, and the price isn't much different.

Pretty sure (not positive, but pretty sure) that my steering box is going bad. It's a daily with 31s so not some super huge monster. Should I go with another stock box or something else?

IIRC certain Durango, S10 and ZJ boxes are drop in, are similar priced new and give a better ratio.

Why did my XJ turn off on the highway then turn back on? Momentarily felt like a weird shift, then noticed the tach at 0, then it fixed itself. Bad battery connections? They seem good. CPS?
