Title: Sammi heat only works on passenger side
Post by: whtsox72 on September 21, 2006, 06:54:09 AM: I have an 88 Sammi and the heat only works on the passenger side. The driver's side blows cold air but the passenger side blows hot air.
Any ideas?

The lower vents are literally right off the heater core so it is impossible to not have heat one one side of the truck there. On the upper vents, defrosters, I guess it can be possible. Just look at yout heater box and make sure that the tube that runs up to those vents is attached and such. Another thing to check is on the ds side of the box, an old sammi trick is to cut a hole in the box and vacuum off the heater core to get rid off all the debris that falls in there. Just take a look and if you have a hole make sure it is sealed good with some duct tape or similar. Prolly half the sammis that I see have this"mod" done, so something to look into

My heat only works on the passenger side. Period. I do not know why it is like this but when I turn on the heat at the floor or the defroster it blows cold air out the driver side.
I do have a hole on the driver side and it looks like someone tried cleaning it out at one time. I have sealed this hole and it does not make a difference.
Where are the tubs that run to the vents at? Can I see them from the engine or do I have to take off the dash to get to them?
I have been looking for a picture of an enginde showing where the heat tubes enter and I cannot find anything.

Post by: whtsox72 on October 11, 2006, 02:00:17 PM: Anyone have good instructions on replacing a heater core?
Or does anyone know if I have to remove the dash to check the ducts for my heat?

Usually the lack of airflow means something is clogged up. Do you see decent airflow when you are using the feet mode?

You shouldn't have to remove the dash, and taking the heater core out is pretty simple. The shop manual has really good instructions, I can probably pick it up and scan the pages this weekend if nobody else posts them.

Post by: DanielW on October 12, 2006, 10:16:24 AM: front air and bottom airflow is great. I was just wondering if the defrost is supposed to be under the amount of airflow that the other airflow selections have.

thankyou for your reply.
