Default Problem with my heat!!

My car will not produce any heat. Since some cold weather has moved into my town in the past few days I have noticed a promblem with my Ti. My engine will not heat up past the blue mark. it gets to the edge of the blue and that is it. I try to use the heat during this time and all I get is cool air. This is not good. I figure that if my car was heating up (to the halfway mark) then maybe my heat would work???? But i am not sure. could someone help me out. I need some heat for the upcoming winter.

You need a new thermostat.

Yep, most likely a thermostat. If you let your car idle (stopped), will it warm up more than if it was rolling? If so, it's the thermostat stuck open.

I recommend using the bleed instructions on understeer.com. http://understeer.com/waterpump.shtml Step#10

When I first bought my ti, I couldn't get it to move past the first white mark. I replaced the thermo and got my heat and the temp gauge to work. I'm going to agree with everyone else and say its the thermostat.

There's a writeup somewhere. Apart from draining the coolant, it's just a bolt-on part.

Two things:
1. Use penetrating spray like Kroil, PB Blaster, etc, preferrably starting the night before to let it soak in. WD40 is crap.
2. To remove the hoses easier, twist them before pulling to break the seal, and twist back and forth while pulling.

Ok I think this problem is past a new thermostat. I have now noticed that the cable for the turn knob must be broken. Because I can not get it to switch from cold to Hot. It just turns and nothing happens from there. I am hoping that someone on this forum could point me in the right direction about how I can get to this cable and possibly fix the situation. Is there a way I can just pull on the broken cable and get it to switch to Heat and not have to buy a new cable????? All and any help is welcome. I can't drive my car when it is 30 degrees outside and I have no heat. My toes freeze and everything else. Plus no heat means no hot chicks............ help me get the chicks back guys.

Hey Will, I had this happen to me a couple of months ago. There was a recall a while back and the dealer was supposed to put a screw through the little yellow tab to hold it in place and keep it from slipping out of it's detent. On my car, the dealer had already performed this mod, but the yellow clip with the screw ripped a big chunk out of my heater box. After several minutes of racking my brain, I decided to ziptie the cable to the steel tubular support frame under the dash where the cable intersects it. With the yellow tab firmly wedged into it's detent, the cable is now snug as a bug. There's no chance of it ever slipping out again and the routing of the cable allows smooth turning of the knob. I tested it about a hundred times before I buttoned everything back up and it works perfectly now. Good Luck, LMK if you have anymore problems getting it to work.

BTW, you'll get better access if you take the glove compartment and kick panel out from the passenger's side legwell.

I went out to my dad's friend's body shop. My dad and me changed the Thermostat with a brand new one. So now my engine temp. is exactly where it should be. The car runs a lot better when it is warm. But my heat is still having a problem. I know now that it is not my cable. When I turn it to heat it begins to get maybe like luke warm or just a few degrees below that but you can tell it is trying. But just not hard enough. Now my dad's friend suggest that it is this small grey thing that is located on the driver's side pretty close to the firewall. He says that it is a water pump that helps the heat or something. I need to confirm this will of you all to make sure that I am headed in the right direction of getting a replacement piece and fixing the problem. Thanks for any help.
