a few problems with my 03 marauder

[htownboss]

i have a few problems with my 03 Marauder. first temp is running high within the first 5 mins of starting up and driving temp goes down eventually a couple people told me it's my tstat im replacing that tomorrow. second the air doesn't come through my vents only thru the dash and the floor. last night my car started making a weird noise then my heater stopped blowing all together. 30 mins later started back blowing. third my car is shifting funny before it switches gears it loses rpm and makes a squeaking noise When it finally shifts. i hope ITZ nothing to major but i don't know what is wrong any ideas guys?

After replacing the t-stat, make sure the cooling system is burped of air pockets fully, or the same will occur.
As for the rest, the a/c control head can be repaired by changing the O-rings and the blower motor controller is going south.

As for the transmission, maybe someone here will chime in on this.

After replacing the t-sat make sure you burp the ssytem to get all the air out.

Sounds like you need the o-rings replacing in your EATC.

Blower motor issues sounds like you need a new BCM.

Check your trans fluid.

The overheating could be as simple as a dirty radiator. Check it out and if it looks bad invest a few quarters at a coin car wash and power wash it, but make sure you don't give it too much power or you can damage it. I have done this twice and fixed my overheating. It was just dirty.

Shifting is normal. The torque converter is locking up. To shift firmer, get a tune, The squeak when it shifts is the belt. Get a Goodyear Gatorback belt and it won't squeak.
