Just finished my'91 sonoma core. Had to take the four screws out nearest the windshield defrost ducts(2 on ea.side)& then take out all the screws on bottom of dash.Also had to take out glovebox & trim.I even took out radio,just to clean dust off it.Pull dash up & out just enough to gain access to your core"box" under the dash Remove 6 screws holding box cover on.Raise hood & where lines go into core box,remove bracket & screws that reinforce the 2 core copper lines & remove the 2 hose clamps & pull hoses back.There will be 2 screws holding the core in the box(under the dash).Remove these 2 screws & pull core out of box. Just reverse procedure for installation.Not a hard job,just time-consuming with a lot of dash screws & a few cuss words.Good luck!
