Heater question

I've searched around for an answer similar to my problem, but I'm not sure if i truly have a "problem" or need to make a change.

Ok, so I finally replaced the blower motor switch in my 00 Sahara and everything works fine, except if I want HOT air, I have to get on the highway and hot rod my Jeep until it reaches 210 or wait forever and a half, which I'm at work or wherever I'm going before it finally gets hot. Otherwise it's warm at best. I don't always have the chance to hot rod it (not that I want to hot rod it) to get it warm. Does anybody have suggestions? Would it be my heater core somewhat clogged? Blend door being stuck? Needs a lower temp thermostat (still running the factory thermostat) like a 180*?

Reading the other threads on heat being just WARM, it was either a clogged heater core or the blend door being stuck. But since mine does get hot (just takes forever), I wasn't sure if those would still be suspect things to check. Any suggestions on whats wrong or do I need to just put in a lower temp thermostat?

A lower temp thermostat wouldn't help at all, stick with the factory 195*. Your heater core might not be plugged, but it may be restricted. When the car has been running feel both the hoses leading to the heater core. There shouldn't be a large difference in their temps. If the hose that runs to the water pump (return line) is noticeably cooler than the line that runs to the thermostat housing (feed line); than your problem is in the heater core.

Yeah I got a four banger, big whoop, wanna fight about it!?

Are you using synthetic oil by chance? I use synthetic oil in all my vehicles, and they all take forever to get up to operating temps. When our weather gets cold, I place a piece of cardboard in front of the radiator. The colder it gets, the bigger the piece of cardboard! Don't block the whole radiator, and keep a eye on your temp guage, and adjust the size of the cardboard to fit your weather. For me, a soda 12 pak opened up is about perfect!

I'll check the hoses today (sorry, didn't realize I had updates...never got an email showing there were new posts lol). Ok, I'll stick with the stock thermostat. As for my oil, I run conventional. I've considered doing a cover for the grill and might end up giving that a try.

Trust me, it won't run cooler with synthetic engine oil. The engine temp is under control of the thermostat. If the engine started running cooler after installing synthetic oil, the thermostat simply coincidentally started sticking open at that time.
When you have a choice, buy American.
