You will find two under the dash, one on each end. Then there are two hidden under the speaker grills on the dash and two more under the center vent grill. There are also two toward the middle of the dash behind the radio plus the ones that secure the dash to the steering column bracket and depending on options the center console has one above it going to a brace. I think that's all. I've slept since I pulled a dash on a 95. :-)

My spec for factory says 2.2 hrs. Sometimes that factory spec isn't realistic. My labor specs says factory--regular--severe, the severe is close to 4 hrs.

It is located under the dash and requires many things to be removed. I recommend that you purchase a repair manual that provides step by step instructions and pictures to identify parts.

Let me know if you have other questions.

We have to re and re the heater core. Is it do-able in a day's time? Also, I have heard that a small section of the air duct can be cut and taped over so u can cut the re and re time down. (It's cold outside. Grinzzz!) Thanks.

Hi:
You could do it in a day. However, I don't recommend cutting things. You'll end up with other problems. I do recommend that you purchase a repair manual because it is involved process.
