I recently took my S10 Pickup to Peterson's to see what was wrong with my heater it wasn't getting hot. Well Peterson's looked at it for me and they told me it would cost about 900$ to fix the problem. They said my heater core and hoses needed to be flushed and my radiator needed cleaning and it had to be pulled out along with pulling my heater core out. If you know anything about cars or trucks the heater core is behind the dash. Well after getting that 900$ estimate, I was like OMG I can't afford that. So i talked to Greer automotive and he told me that was BS I didn't need to pull the heater core to just take the hoses off and blow it with air. OMG IT REALLY WORKED I HAVE HEAT NOW AND IT ONLY COST 22$ FOR THE HOSES AND 2 HOURS OF WORK. If u ever take your vehicle to PETERSON'S GET A SECOND OPINION. I DID!!!
