Heat problems!! Please help !!
About a month ago my truck sensor said I was overheating. Naturally I got some anti freeze and put some in the radiator and the overflow. The next day the truck was not pushing warm air in the cab. (It had before) I found out my radiator had a leak and that's why I was overheating, so I changed the radiator, the thermostat (195 degree), the water pump, the heater core and my blend door moves, I can hear it. Now the fan speed **** only works on high, I have no idea if this is relevant to my problem but I have tried everything I can think of.
My truck is a 1995 K1500
Please help with suggestions. Thanks

My,blower only blows, on high or on 2 also, since I owned truck? 98 . I recently put new t-stat in cause wasn't getting warm enough. Now I have 150 deg air nice, but my 195 stat still opens at like 155, and truck still runs cooler than should. Tested w/ non contact can't afford scan tool. Sounds and seems like my fan clutch always engaged too is that common ? Sorry for hijacked

you have 2 issues, the resistor (most likely) will fix the blower so all speeds work.
as far as the no heat feel hoses, in and out of the radiator and same with the heater core and also just because you put a new tstat in doesn't mean its a good 1. Does the gauge read where it should? A scanner would be very helpful to see the ECT reading

The gauge reads well it sits just before 210 (half) when it's been running for a while.
