1999 Blazer- Just replaced Rear main seal and oil pan gasket , had 93,00 mile on it. Had to remove Transfer case, Trans. and differential. Gas guage does not work. Everthing in cluster works except fuel guage .Lite says low fuel.Tank is full.Never had problem with fuel guage.Guage reads empty. This is a 99 automatic with 4.3. Any help.
Also 4 wheel drive switch lights (dash) flash except in 2 wheel Hi.This has 3 switches and a automatic button also.When I try to switch to 4 Hi or low all I have is a flashing lite. when I put back into 2 hi light works fine. Any suggestions.
