Odd Problem

wow198073 on Thu October 28, 2010 4:41 PM User is offline

Year: 2002
Make: Chevy
Model: Cavalier
Engine Size: 2200
Refrigerant Type: r134
Ambient Temp: 75
Pressure Low: 30
Pressure High: 225

ok my problem started when i got the car.

i had no heater but i had a/c.....
spun a bearing....

after motor swap, i have blazing hot heater but no a/c

recently, blower stopped working and come to find out it was a plug in the back of my ignition switch.

here are the specs

low - 30
high - 225
clutch will not engage
blower blows room temp air on a/c
blower blows hot air on heater
there is a maple smell..... i was told this could be a resistor pack OR heater core and most likely its the heater core....

much help would be appreciated

Sound like you may have a blend door issue…. You say the clutch will not engage, but then you have gauge readings as if it is on? Are the pipes getting cold out side on the accumulator?

The smell sounds like a bad heater core leaking….

A/C clutch is engaging according to the pressures. From your description, I would guess old engine had cooling system clogs and flow issues (i.e. no heat). New engine cooling flow is now producing heat. Blend door problem (mixing hot and cold air) may have been an existing issue; previously it just had no hot air to add. Pinch off heater hose flow to the heater core and see if you have cold air. Sweet smell may indicate antifreeze leak in the heater core.
