the defroster blows heat out one side and cold air out the other. i was told it was the air distributor. the book says it is non serviceable so i guess i`ll have to replace it. ron

Do any other air modes blow cool on one side and heat on the other? Go through all modes of operation and see if other abnormalities exist.

driver side on floor is about 15 degrees cooler, dash vents are same because they come off the same y. the degree difference is larger in winter time because out side air is colder.

I could use this also. My '92 blower is running on high but does not blow strong out the vents or move enough air to keep the car cool even though the A/C system is working fine.

I would start by checking for a restricted heater core or restricted air across the evaporator. Next get the heater core cover off to inspect the air mix door ( it's behind the A/C programmer which is behind the glove box).

Mustang661, start with the evap inspection
