Hello every one,

97 T100 V6 5spd 4WD ext cab

IÆm having problem with my air conditioner.
When it stoped cooling (coolant loss ???) I have attempted to recharge it.
After applying 1 can of 134a it was cooling again.
Unfortunately when driving to work next day I could smell coolant in the cabin.
It looks like the coolant was being pumped into the cabin through the cabinÆs vents.
I believe that problem is with a cooling unit û evaporator to be exact.
Is evaporator exchangeable or it would be entire unit?

Anybody experienced similar problem?
How did you fix it?

Any suggestions appreciated.

Thanks.
