Defrost problems 87 R2500 7.4 liter
When I switch to defrost, it barely blows out the defroster vents and blows mosltly out the front dash vents. I located the vacuum switch by the tranny hump and it appears to be working. Must be another one up top somewhere?? Don't have a book on this truck.
Any help would be appreciated. The truck is a 1987 bigblock with AC. Thanks, Greg |
